Question

The sides of an isosceles triangle are 8, 8, and 3. The measure of the vertex angle to the nearest degree is

44
17
31
22

Answer 1

22

Explanation:

Any triangles angles will add up to 180 degrees. So first we are gonna find the two bottom angles. They are both about 79 degrees. so we need to add 79+79 to get 158. now all we have to do is subtract 158 from 180 (180-158) and get your answer 22 degrees

hopefully this helped you :)
