Angle 1 and angle 2 are supplementary angles. m angle 1 is 4y+7. and m angle 2 is 9y+4. find the measure of angle 2
show work

the measure of the angle 2  is 121 degrees

Step-by-step explanation:

Hello

Supplementary angles are two angles whose measurements add up to 180

m1+m2=180

m1 and m2 are supplementary angles

Step 1

Let

m1+m2=180

(1)m1=4y+7

(2)m2=9y+4

hence

4y+7+9y+4=180

resolving for y

13y+11=180

subtract 11 in each side

13y+11-11=180-11

13y=169

Now, divide each side by 13

(13y)/13=169/13

y=13

Step 2

Now , put the value of y=13  in (1) and (2) to find m1 and m2

(1)m1=4y+7

m1=4(13)+7

m1=59

m2=9y+4

m2= 9(13)+4

m2=117+4

m2=121

the measure of the angle 2 (m2) is 121 degrees

have a great day.
