Answer 2

In the above diagram,

Three angles are = 135°, 120° and and x °

Let us assume that the angles be <A, <B and <C.

Interior angles be PQR.

<A + <P = 180° { Linear pair }

135° + <P = 180°

<P = 180° - 135°

<P = 45°

<B + <Q = 180° { Linear pair }

120° + <Q = 180°

<Q = 180° - 120°

<Q = 60°

Then,

<C = x°

From above,

<C = <A + <B { Exterior angle = Sum of two interior angles }

<C = 45° + 60°

<C = 105°

Therefore, x = 105°
