Question

In the adjoining figure, the value of x that will make AOB a straight line is ​

Answer 1

Answer:

Given,

Angel AOC = (3x + 15)°

Angel COB = (2x - 10)°

A/q

=> 3x + 15 + 2x - 10 = 180°(Because of lineral pair)

=> 5x + 5 = 180°

=> 5x = 180° - 5°

=> 5x = 175°

=> x = 175°/5

=> x = 35°

Therefore, x = 35°
