The altitude of an isosceles triangle bisects the base and measures 10ft. If the base of the triangle measures 16ft, calculate: a) the area of the triangle b) and one side of the triangle.
Answer:
Step-by-step explanation:
the formula for calxulating the area if the isosceles triangle is expressed as;
[tex]A = \frac{1}{2}bh[/tex]
b is the base of the triangle
h is the altitude
Given
b = 16ft
h = 10ft
Substitute
A = 1/2 * 16 * 10
A = 8*10
A = 80ft²
Hence the area of the triangle is 80ft²
b) To get the measure of one side of the triangle, we will use the pythagoras theorem. Let s be the slant side
s² = h²+(b/2)²
s² = 10²+(16/2)²
s² = 10²+(8)²
s² =100+64
s² =164
s = √164
s = 12.8ft
Hence one side of the triangle is 12.8ft

20 divided by 2.5 is 8
Answer:
Step-by-step explanation:
to answer this question, you need to set up a preportion.
15 = 6
20 x
then we would multiply 15 by x, and 20 by 6.
20(6) = 120
120= 15x
120 divided by 15 is:

Answer:
The firefighter should extend the ladder at 54° of elevation.
Step-by-step explanation:
Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
Tangent Ratio:
[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
The woman is trapped at 91 feet up from the ground, and the firetruck is 67 feet away from the building.
The wall, the ground, and the ladder form a right triangle, where θ is the horizontal angle of the ladder.
Being the height of the woman the opposite leg and the distance where the firetruck is parked, the adjacent leg:
[tex]\displaystyle \tan\theta=\frac{91}{67}=1.3582[/tex]
The angle is calculated as the inverse tangent:
[tex]\theta=arctan(1.3582)\approx 54^\circ[/tex]
The firefighter should extend the ladder at 54° of elevation.

Resolve into factors:- 9x4 + 2x²y²+ y4
Answer:
(3x^2+y^2+2xy)(3x^2+y^2-2xy)
Step-by-step explanation:
9x^4+2x^2y^2+y^4
(3x^2+y^2+2xy)(3x^2+y^2-2xy)
Both terms are perfect squares. So you will factor using the difference of squares formula. a^2-b^2=(a+b)(a-b)
Take what the square is for every term.
9x^4. What squared is 9? 3 and take half of the power or 2. That's how you get the 3x^2
2x^2y^2 is the same way. 2xy and 2xy
y^4 is y but dived he powers by 2 to get y^2.
Take one of each and but in () like I have above.
Write this statement as a conditional statement in the form “if p, then q.”
A ray divides an angle into two congruent angles. So, the ray is an angle bisector.
Answer:
if a ray divides an angle into two congruent angles, then the ray is an angle bisector.
Step-by-step explanation:
if p statement is before the comma, called the hypothesis of the conditional statement.
then q statement is after the comma and it is called the conclusion of the conditional statement.

What is the slope??? PLEASE HELP!!!
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

Joe borrowed $6,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 4 years?
Answer:
Joe would be paying $700 in 5 years time.
Step-by-step explanation:
Answer:
In 4 years Joe would have to pay $1,680 in simple interest.
Step-by-step explanation:
So first of all you want to start by finding what P, r and t would be.
P = Principal amount ($$)
r = interest rate (%)
t = time
Once I found all of those I put them into the equation (l = Prt) and solved. That is how I came up with my answer. Check the screenshot provided to see what P, r and t would be and to see all my work! :)

Nathan is using his grandmother's recipe to make pies
On Monday, he used 15 3/4 cups of sugar to make 9 pies
On Tuesday, he used 23 3/4 cups of sugar to make 13 pies
Which of the following must be true? (Select all that apply)
A) He used 1 cup of sugar for every 1 3/4 pies he made
B) He would use 14 cups of sugar to make 8 pies
C) The number of cups of sugar is proportional to the number of pies he made because he used the same number of cups of sugar for each pie
D) The number of cups of sugar is not porptional to the number of pies he made because the increase in the number of cups of sugar between Monday and Tuesday is greater than the increase in the number of pies
E) if Nathan uses 8 3/4 cups of sugar to make 5 pies on Wednesday and then graphs the points, for all the three days, to represent the relationship between the cups of sugar used and the number of pies made, the points would not fall on a straight line

Right triangle ABC is similar to Right triangle XYZ. The value of cosB = 5/13. What is the value of sin Y?
Answer:
if sin B = sin Y then sin Y = 12/13
Step-by-step explanation:
Triangle ABC is similar to Triangle XYZ
Let angle C be the right angle
Cosine of B is equal to 5/13
Cos B = adjacent/hypotenuse = 5/13
NOTE = below is the lowercase letters that represent the side lengths, not the angles
Adjacent (length of a) = 5 <-- given
Hypotenuse (length of c) = 13 <-- given
Opposide (length of b) = a^2 + b^2 = c^2 --> 5^2 + b^2 = 13^2 --> b = 12
sin B = sin Y
sin B = opp/hyp = 12/13
if sin B = sin Y then sin Y = 12/13
