Answer 2

SOLUTION

GIVEN

The measurement of two interior opposite angles of a triangle is 50° and 70° .

TO DETERMINE

The measure of its exterior angle

CONCEPT TO BE IMPLEMENTED

EXTERIOR ANGLE THEOREM

The measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.

EVALUATION

Here it is given that measurement of two interior opposite angles of a triangle is 50° and 70° .

So by the exterior angle Theorem ,

The measure of its exterior angle

= 50° + 70°

= 120°
