Question

What is m < A what is m what is m

Answer 1

∠ A = 50°

Explanation:

the angle inside the triangle and 85° are adjacent angles and sum to 180°

180° - 85° = 95°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

145° is an exterior angle of the triangle , then

∠ A + 95° = 145° ( subtract 95° from both sides )

∠ A = 50°
