Question

Answer the Question. ​

Answer 1

Answer:

given:

measure of exterior angles = 80°

measure of one of the opposite interior angles is 25°

to find:

measure of the other opposite interior angle = ?

we know that exterior angles of a triangle is equal to the sum of its two opposite interior angles.

therefore,

let the other opposite interior angle be y

y + 25° = 80°

y = 80° - 25°

y = 55°

measure of the other opposite interior angle is 55°
