Question

D
1.
An isosceles triangle has two base angles equal to 13 degrees. What is the
measure of the third angle?
O
26 degrees
O
154 degrees
O
184 degrees
206 degrees

Answer 1

154 degrees.

Triangles add up to 180 and the known angles are 13 degrees each, or 26 together.
180-26=154, which is the measure of the missing angle.
