By exterior angle theorem,

Exterior angle = Sum of interior opposite angles

Let each interior opposite angles = x

105=x+x

105=2x

x=52 1°/2 ( 52 . 5 )

Answer 2

Answer:

let the interior opp angle be x

since both the angles are equal, both of them would be x

ATQ

x+x= 105° (sum of two opp interior angle is equal to exterior angle)

2x= 105°

x= 105/2

x= 52.5°

hence both the opp equal angles will be of 52.5°
