The third angle of an isosceles triangle is 16 o less than the sum of two equal angles. Find

vodka [1.7K]

Answer: 49°, 49°, 82°

Step-by-step explanation:

Let x represent the base angles

then 2x - 16 is the vertex angle.

Triangle Sum Theorem states that the sum of the angles is 180°

(x) + (x) + (2x - 16) = 180

4x - 16 = 180

4x = 196

x = 49

Base angles: x = 49

Vertex angle: 2(49) - 16 = 82
