Note: enter your answer and show all the steps that you use to solve this problem in the space provided. ∠ 1 and ∠ 2 are supplementary angles. m ∠ 1 is 4 y + 7 , and m ∠ 2 is 9 y + 4 . find m ∠ 2 .

m∠2=121°

Step-by-step explanation:

we know that

If two angles are supplementary, then their sum is equal to 18 degrees

In this problem

m∠1+m∠2=180° ---> equation A

we have

m∠1=(4y+7)°

m∠2=(9y+4)°

substitute in the equation A and solve for y

Find the measure m ∠ 2

m∠2=(9y+4)°

substitute the value of y

m∠2=(9(13)+4)=121°

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
