Question

Help! please i’m stuck

Answer 1

There are two equal sides of 8, which means this is an isosceles triangle. With an isosceles triangle, there are also two equal angles (30° each in this case). If angle C equals 30°, then angle B also equals 30°. Subtract angles B and C from the total degrees in a triangle.


Triangles Degrees= 180° total

Find angle A:
= total triangle degrees - < B - < C
= 180° - 30° - 30°
= 120°


ANSWER: Angle A is (B) 120°

Hope this helps! :)
