Question

An exterior angle of a triangle is 105 and its two interior opposite girls are equal. Each of these equal angles is

Answer 1

exterior angle = 105

we know that sum of two interiors angles is equal to an exterior angles

let two interior angle be x

x+x=105

2 x=105

x=52.5

we know that sum of three angles of triangle is 180

x+x+third angle =180

52.5+52.5+third angle = 180

105 + third angles=180

third angle = 180-105

third angle =75
