Answer 2

Question:-

• Find the value of unknown angles from the figure.

Solution:-

We know that,

interior angle + exterior angle=180°

So

b+110°=180°

>> b=70°

We know that,

Exterior angle = Sum of opposite two interior angles.

So,

40°+a=110°

>> a=70°

Hence,

a=70°

a=70°b=70°

Answer:-

• a=70° and b=70°
