Question

Given angle POR = 3x and angle QOR = 2x + 10 degree . If POQ is a straight line ,then the value of x is

​

Answer 1

Step-by-step explanation:

3x + 2x + 10 = 180 (linear pair)

5x = 170

x = 34

Answer 2

Step-by-step explanation:

∠POR + ∠QOR = 180° [Angles of a linear pair]

=> 3x + 2x + 10° = 180°

=> 3x + 2x = 180° - 10°

=> 3x + 2x = 170°

=> 5x = 170°

=> x = 170° ÷ 5

=> x = 34

Hence, the value of x is 34°

Hope this helps!
