Question

(y+20) and 3y are supplymentary Angles then find the measure of each angle​

Answer 1

Answer:

The angles are 120 and 60

Step-by-step explanation:

GIVEN:

(y+20) and 3y are supplymentary Angles

ATQ,

(y+20) + 3y = 180

4y+20=180

4y=180-20

4y=160

y=160/4

y=40

the angles are:

y+20=40+20=60

3y=3(40)=120

The angles are 120 and 60
