Answer:

y = (8/7)x

Step-by-step explanation:

We can see that this line intersects with the points (0,0) and (21,24).

The equation of this line is y=mx (y-intercept is 0).

The slope is the change in y over the change in x.

24-0/21-0 = 24/21 = 8/7

y = (8/7)x

Hope this helps!

Two angles are complementary angles if the sum of their measure is 90 degrees. Angle A and angle B are complementary angles, and
Marta_Voda [28]
Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

We will be using simultaneous equations to solve this problem.

First we will establish the equations which we will be using as displayed below:

Equation No. 1 -

A + B = 90°

Equation No. 1 -

A = 2B + 12

To begin with, let's make ( A ) the subject in the first equation as displayed below:

Equation No. 1 -

A + B = 90

A = 90 - B

Next we will substitute the value of ( A ) from the first equation into the second equation and solve for ( B ) as displayed below:

Equation No. 2 -

A = 2B + 12

( 90 - B ) = 2B + 12

- B - 2B = 12 - 90

- 3B = - 78

B = - 78 / - 3

B = 26°

Then we will substitute the value of ( B ) from the second equation into the first equation to solve for ( A ) as displayed below:

A = 90 - B

A = 90 - ( 26 )

A = 64°

ANSWER:

Therefore, the answer is:

A = 64°

B = 26°

Please help I don’t understand it’s like angles and stuff picture above.
dusya [7]

Answer:

1) 145°

2) 20°

3) x = 7 ; measurement of the missing angle = 24

Step-by-step explanation:

1) supplement = 180°, 180 - 35 = 145

2) complment = 90° , 90 - 70 = 20

3) the figure is a right angle so the measurement is 90°

66 + (4x-4) = 90

62 + 4x = 90

4x = 28

x = 7

4(7) - 4

28 - 4

= 24
