Question

in the given degree ,x=30°,calculate the value of y.

Answer 1

Answer:

Step-by-step explanation:

2x+3y=180  (linear pair angle)

2*30+3y=180

60+3y=180

3y=120

y=120/3

y=40°

Answer 2

Answer:

x=30(given)

2x=2*30=60

x=60

3y+60=180(sum of two angles on a line is=180)

3y=180-60

3y=120

y=40
