Step-by-step explanation:
First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.

29. Find the measure of each angle.
E
с
(5x + 2)
3x
B
Answer:
The measure of each angle is :
3x° = 33°
(5x+2)° =57°
Step-by-step explanation:
From the diagram, angle <ABC is a right-angle triangle with a measure of 90°
This means the sum of the two angles <ABE + <CBE =90°
Given from the question :
<ABE = 3x°
<CBE = (5x+2)°
For an equation for sum of the two angles as;
<ABE + <CBE =90°
3x° + (5x+2)° = 90° ------collect like terms after opening the brackets
3x° +5x° + 2° =90°
8x°=90°-2°
8x°=88°
x°=88°/8° = 11°
Measure of the angles will be:
<ABE = 3x° = 3*11° = 33°
<CBE = (5x+2)° = (5*11° +2° ) =55°+2°= 57°
Answers are :
3x° = 33°
(5x+2)° =57°

Answer:
2) 162°, 72°, 108°
3) 144°, 54°, 126°
Step-by-step explanation:
1) Multiply the equation by 2sin(θ) to get an equation that looks like ...
sin(θ) = <some numerical expression>
Use your knowledge of the sines of special angles to find two angles that have this sine value. (The attached table along with the relations discussed below will get you there.)
____
2, 3) You need to review the meaning of "supplement".
It is true that ...
sin(θ) = sin(θ+360°),
but it is also true that ...
sin(θ) = sin(180°-θ) . . . . the supplement of the angle
This latter relation is the one applicable to this question.
__
Similarly, it is true that ...
cos(θ) = -cos(θ+180°),
but it is also true that ...
cos(θ) = -cos(180°-θ) . . . . the supplement of the angle
As above, it is this latter relation that applies to problems 2 and 3.
Jerry is standing next to a big tree. The tree casts a shadow that is
20 feet long. Jerry, who is 6 ft tall, casts a shadow that is 2 feet
long.
How tall is the tree?
Answer: The tree has to be 60 feet tall
Step-by-step explanation: Jerry’s shadow is a third of Jerry, that means the Tree’s shadow is only a third of the tree. To find the tree’s height you have to multiply the shadow by 3, 20 multiplied by 3 is 60.

What is the distance between (4, 7)(4,7)left parenthesis, 4, comma, 7, right parenthesis and (2, 2)(2,2)left parenthesis, 2, comma, 2, right parenthesis? Choose 1 answer: Choose 1 answer: (Choice A) A \sqrt{10} 10 square root of, 10, end square root (Choice B) B \sqrt{29} 29 square root of, 29, end square root (Choice C) C 888 (Choice D) D 99
Answer:
Choice B) B \sqrt{29} 29 square root of, 29, end square root = √29
Step-by-step explanation:
When given coordinates, the distance between those points(coordinates) is calculated as:
Distance = √(x2 - x1)² +(y2 - y1)²
Given(x1, y1), (x2, y2)
Fromm the question, we are given points(4,7) and (2,2)
Distance = √(x2 - x1)² +(y2 - y1)²
= √(2 - 4)² + (2 - 7)²
= √-2² + -5²
= √4 + 25
= √29
Therefore, Choice B is the answer = √29
Clay went for a run to prepare for a long distance race co ran 6 miles directly north and then 8 miles directly west. From there, he ran the diagonal distance back to his house. How many total miles did Clay run?
Answer:
24 miles
Step-by-step explanation:
so he went 6 miles, then 8 miles, then diagonally home.
which means he ran in a triangle.
Use the Pythagorean theory.
6*6=36
8*8=64
36+64=100
what square root = to 100?
10
so the questions is total moles did clay run.
6+8+10=24 miles

How do you illustrate
quadratic equation
in one variable?
Step-by-step explanation:
Quadratic Equation
Quadratic equation is in the form
ax2+bx+c=0
Where
a, b, & c = real-number constants
a & b = numerical coefficient or simply coefficients
a = coefficient of x2
b = coefficient of x
c = constant term or simply constant
a cannot be equal to zero while either b or c can be zero
Examples of Quadratic Equation
Some quadratic equation may not look like the one above. The general appearance of quadratic equation is a second degree curve so that the degree power of one variable is twice of another variable. Below are examples of equations that can be considered as quadratic.
1. 3x2+2x−8=0
2. x2−9=0
3. 2x2+5x=0
4. sin2θ−2sinθ−1=0
5. x−5x−−√+6=0
6. 10x1/3+x1/6−2=0
7. 2lnx−−−√−5lnx−−−√4−7=0
For us to see that the above examples can be treated as quadratic equation, we take example no. 6 above, 10x1/3 + x1/6 - 2 = 0. Let x1/6 = z, thus, x1/3 = z2. The equation can now be written in the form 10z2 + z - 2 = 0, which shows clearly to be quadratic equation.
Roots of a Quadratic Equation
The equation ax2 + bx + c = 0 can be factored into the form
(x−x1)(x−x2)=0
Where x1 and x2 are the roots of ax2 + bx + c = 0.
Quadratic Formula
For the quadratic equation ax2 + bx + c = 0,
x=−b±b2−4ac−−−−−−−√2a
See the derivation of quadratic formula here.
The quantity b2 - 4ac inside the radical is called discriminat.
• If b2 - 4ac = 0, the roots are real and equal.
• If b2 - 4ac > 0, the roots are real and unequal.
• If b2 - 4ac < 0, the roots are imaginary.
Sum and Product of Roots
If the roots of the quadratic equation ax2 + bx + c
= 0 are x1 and x2, then
Sum of roots
x1+x2=−ba
Product of roots
x1x2=ca
You may see the derivation of formulas for sum and product of roots here.

Joel used a half gallon of paint to cover 84 square feet of wall he has 932 square feet of walls of paint how many gallons of paint should you purchase
Answer:
About 6 gallons of paint
Step-by-step explanation:
[tex]\frac{0.5}{84}[/tex] = [tex]\frac{x}{932}[/tex]
84x=932(0.5)
84x=466
x = 5.55
round up to get about 6 gallons of paint
The number of the gallon of paint is need will be 5.547 gallons of paint.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Joel used a half gallon of paint to cover 84 square feet of wall.
Then in one gallon of paint he can cover 168 square feet.
He has 932 square feet of walls of paint.
Then the number of the gallon of paint is need will be
⇒ 932 / 168
⇒ 5.547 gallons of paint

find x, if ∠1 and ∠2 are a linear pair. m∠1 = 20+5x and m∠2 =x+10
Answer:
[tex]\boxed { x = -\frac{5}{2}}[/tex]
Step-by-step explanation:
To determine the value of [tex]x[/tex], write expression by using the following measurement from both [tex]\angle 1[/tex] and [tex]\angle 2[/tex] and solve:
[tex]\angle 1 = 20 + 5x[/tex]
[tex]\angle 2 = x + 10[/tex]
[tex]20 + 5x = x + 10[/tex]
Solve for [tex]x[/tex]:
[tex]20 + 5x = x + 10[/tex]
[tex]20 + 5x - x = x - x + 10[/tex]
[tex]20 + 4x = 10[/tex]
[tex]20 - 20 + 4x = 10 - 20[/tex]
[tex]4x = -10[/tex]
[tex]\frac{4x}{4} = \frac{-10}{4}[/tex]
[tex]\boxed { x = -\frac{5}{2}}[/tex]
So, the value of [tex]x[/tex] is [tex]-\frac{5}{2}[/tex].
A triangle has sides with lengths of 38 feet, 56 feet, and 69 feet. Is it a right triangle?
Answer:
No
Step-by-step explanation:
Assume that it is a right triangle for now
According to the Pythagorean Theorem...
(38)^2 + (56)^2 = (69)^2
4580 ≠ 4761
Both sides are not equal, and hence the Pythagorean Theorem can't be applied to the triangle. It is not a right triangle.
