Question

An isosceles triangle has an angle that measures 126°. Which other angles could be in that isosceles triangle? Choose all that apply.

27°
69°
127°
17°

Answer 1

27

Explanation:

Since triangles have only 180 degrees in a triangle we can rule out the option that 126 degrees is another angle. So subtract 126 from 180 and you get 54. Then you divide 54 by 2 and get 27.
