Question

An isosceles triangle has an angle that measures 120°. Which other angles could be in that isosceles triangle? Choose all that apply.

a.40°

b.50°

c.70°

d.30°

Answer 1

C 30°

Explanation:

All angles in a triangle add up to 180°

180 - 120 = 60

It's an isosceles triangle so, 2 sides are equal, 60° divided by 2 is 30°
