Answer 1

Answer:

<A0B is a linear pair

and linear pair = 180°

Therefore,

<AOC + <BOC = <AOB

(2x - 10) + (3x + 20) = 180

2x - 10 + 3x + 20 = 180

5x + 10 = 180

5x = 180 - 10

5x = 170

x = 34

Hence,

(2x - 10) = 2 × 34 - 10 = 58°

(3x + 20) = 3 × 34 + 20 = 122°

So,

<AOC + <BOC = <AOB

58° + 122° = 180°

180° = 180°

Ans- x = 34°
