Question

Two exterior angles of a triangle equal 100° and 150°. Find all the interior angles

Answer 1

180°-100°= 80° (angle 1)
180°-150°= 30° (angle 2)

180°-80°-30°= angle 3
angle 3 = 70°

∴ the interior angles are 80°, 30° and 70°

Answer 2

Answer:

80,30,and 70

Step-by-step explanation:

180-100=80

180-150=30

80+30=110

180-110=70
