Question

An exterior angle of a triangle is 120° and one of its interior opposite angles is 2 times the other. Find the measure of the greater interior opposite angle of the triangle.

Answer 1

Answer:

Larger opposite angle = 80

Step-by-step explanation:

Let smaller interior angle be x

Greater opposite interior angle = 2x

2x + x = 120......Exterior angle is equal to sum of interior opposite angle

3x = 120

x = 40

Larger angle = 2x = 80
