12. What Type Of Triangle Is Shown?

Answers

Answer 1

Answer:

Scalene triangle, right triangle.

Step-by-step explanation:

To find out what type of triangle this is, we have to find x, so we set up an equation:

The sum of interior angles in a triangle add up to 180°

(2x + 15°) + (4x - 10°) + (x) = 180°

Open paranthesis:

2x + 15° + 4x - 10° + x = 180°

Combine like terms:

7x +  5° = 180°

Same to both sides

7x = 175°

x = 25°

We plug in x for each of the values:

2(25°) + 15° = 65°

4(25°) - 10° = 90°

25° = 25°

Because none of the angles are equal, that makes this triangle a scalene triangle, and since one of the angles is a 90° angle, that makes this triangle a right triangle

I hope this helped, let me know if you have any questions.

Rewrite the equation y – 4x = –9 in slope-intercept form. simple explanation and proof

Answers

Answer:

y=4x-9

Step-by-step explanation:

add 4x to both sides to isolate y

Answer:

The slope-intercept form of this equation would be y = 4x - 9.

(For explanation look down below)  

Step-by-step explanation:

Slope-intercept form would be an equation that would look like...

y = mx + b

Where m is the slope and b is the intercept. From this form, we can understand that all we need to do is rearange the formula in a way that positive y would be on its left side. And so we get...

y - 4x = - 9

y - 4x + 4x = - 9 + 4x

y = 4x - 9

The total cost will cost be the same at each shop for 60 pictures.

What is word problem?

Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement.

Let for x number of picture, the total cost will cost be the same at each shop.

Total cost of x number of picture on Photos fast shop = $ (2.50 + 0.05x)

Total cost of x number of picture on Photos quick shop =  $ (3.70 + 0.03x)

according to the question:

(2.50 + 0.05x) = (3.70 + 0.03x)

0.05x - 0.03x = 3.70 - 2.50

0.02x = 1.20

x = 1.20 ÷ 0.02

x = 60

Hence, for 60 number of picture, the total cost will cost be the same at each shop.

A linear equation is an equation in which each term has at max one degree. The correct option is D, y = -x + 56.

What is a linear equation?

A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form,

y = mx + c

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

Given that the temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Therefore, an equation in slope intercept form to represent the temperature of the day at any given hour is,

y = 56 - x

y = -x + 56

Hence, the equation in slope intercept form to represent the temperature of the day at any given hour is y = -x + 56.

The volume of a thing is the area that it takes up in three dimensions. Simply put, objects occupy space.

Given, the radius of the glass container is 2 inches and height is 3 inches.

To fill the maximum wax in the glass container,

we will find the volume of glass container.

Volume of glass container

What is an equation of the line that passes through the point (6,1) and is perpendicular to the line 2x+3y=18?

Answers

Answer

y = 3/2x -8

Step-by-step explanation:

The first thing you should do is change the equation into slope intercept form. Subtract 2x from both sides to get: 3y = -2x + 18. Divide all parts of the equation by 3 to get your equation in slope intercept: y = -2/3x + 6. One thing you should know when finding the slope of a perpendicular line is that it is the opposite reciprocal. So, the slope is going to be 3/2. This is your current equation: y = 3/2x + b. Plug in the point to the equation, it should look like this: 1 = 3/2(6) + b. Multiply 3/2 by 6 to get 9. This is what it should look like: 1 = 9 + b. Then, subtract 9 from both sides of the equation to get your y-intercept of -8. Go back to your other equation and plug in -8 for b. This is your final equation: y = 3/2x -8.

Answer:

x = 110°

Step-by-step explanation:

∠ QRS = ∠ YRT = 110° ( vertically opposite angles )

∠ PQR = 180° - 120° = 60° ( adjacent angles )

The sum of the interior angles of a quadrilateral = 360°

Sum the angles and equate to 360°, that is

110 + 60 + x + 80 = 360

250° + x = 360° ( subtract 250° from both sides )

x = 110°

Calculate the values of angles A and C of triangle ABC, where b =17.23cm,c=10.86cm and B=10 1 degree 15

Answers

Answer:

C = 38.18°;  A = 40.57°

Step-by-step explanation:

B = 101' 15"

B = 101° + (15/60) = 101 + 0.25 = 101.25°

b =17.23cm,c=10.86cm

From Sine rule :

c/ sin C = b / Sin B

10.86 / sin C = 17.23 / sin 101.25

SinC = (sin 101.25 * 10.86) / 17.23

Sin C = 10.651328 / 17.23

Sin C = 0.6181850

C = Sin^-1(0.6181850)

C = 38.183716

C = 38.18°

Sum of angles in a triangle = 180°

A +  B + C = 180°

A + 101.25° + 38.18° = 180°

A = (180 - (101.25 + 38.18))

A = 40.57°
