Question

one of the exterior angles of a triangle is 80 and interior opposite angles are equal to each other what is the measure of each of these two angles

Answer 1

Step-by-step explanation:

Let both of the two interior angles equal to 'x°'

We know that sum of two opposite interior angles is equal to the exterior angle.

Then, 2x = 80°

x = 40°

Both the angles = 40°

Answer 2

Step-by-step explanation:

let the interior angles be x

since both interior angles are equal

so ,

exterior angle = sum of both interior opposite angles

=> 80° = x+x

=> 80° = 2x

=> 80°/2 = x

=> 40° = x

each interior opposite angles measures 40°
