Question

In an isosceles triangle, the vertex angle is 112 degrees. What is the measure of each base.

Answer 1

Answer:

A

Step-by-step explanation:

The base angles of an isosceles triangle are congruent

The sum of the 3 angles in a triangle = 180°, hence

180° - 112° = 68°

base angle = $\frac{68}{2}$ = 34°

Thus each base angle equals 34° → A
