Look : angle 1 + angle 3 = 180°

because it is a straight line.

Thus ;


5x + 35 + 4x + 10 = 180

Simplification


9x + 45 = 180

Subtract sides 45


9 x = 180 - 45


9x = 135

Divided sides 9


(9)/(9)x = (135)/(9) \\


x = 15

So x = 15°

_________________________________

angle 1 = 5x + 35°

angle 1 = 5 ( 15 ) + 35°

angle 1 = 75° + 35°

angle 1 = 110°

_________________________________

angle 1 + angle 2 = 180°

110° + angle 2 = 180°

Subtract sides 110°

angle 2 = 180° - 110°

angle 2 = 70°
