Question

An exterior angle of a triangle is 110° and one of the interior opposite angles is 30°. Find the other two angles of the triangle​

Answer 1

Step-by-step explanation:

Angle 1 = 30°

Exterior angle = 110°

Angle 2 = 180 - 110 = 70°                 ( Linear Angle Property )

Angle 3 = 180 - 70 + 30 = 80°          ( Angle Sum Property )

Hence the 3 angles of the triangle are 70°, 30° and 80°
