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°
