Answer 1

Answer:

Sol. 1)

Since, corresponding angles are equal to each other

Therefore,

( 2x + 20 )° = ( 3x - 10 )°

2x - 3x = - 20° - 10°

- x = - 30°

so, x = 30°

Sol. 2)

Since sum of Co-interior angles is 180°

Therefore,

(2x)° + ( 3x + 20 )° = 180°

5x + 20° = 180°

5x = ( 180 - 20 )°

x = 160°/ 5

so, x = 34°
