Question

An isosceles triangle has an angle that measures 30°. Which other angles could be in that isosceles triangle? Choose all that apply.

Answer 1

the other angles would have to be 75 degrees each

Explanation:

All of the angles in a triangle make up 180 degrees. an isosceles triangle has 2 angles that are the same and 1 that is different. Since you were given that 30 degrees, you would subtract that from 180, which would give you 150. Since the angles would have to be equal to each other, you would divide 150 by 2 and you would get 75.

Answer 2

Another 30° and a 120°

OR

Two 75°

(I'm not accurate because there is no image)

This is because all triangles MUST add up to 180° and that is the only way for that to happen. Sorry for the short explanation, I hope it still helps.
