a triangle is 40°. If the measure of the

exterior angle is 120°

, find the measure of

the other two angles of the triangle​

Answer 1

Answer:

120-40=80(exterior angle property)

let the other angle be x

x+80+40=180(angle sum property of triangle)

x=180-120

x=60

Answer 2

Answer:

The other angles are 60° and 80°.
