Question

HELP ASAP PLEASE!!!

What is the degree measure of ABC given that A=25 & C=135?

Answer 1

m∠ABC = 110°

Explanation:

By the property of exterior angle of a triangle,

"Exterior angle of a triangle is equal to the sum of two opposite interior angles"

m∠BAC + m∠ABC = 135°

25° + m∠ABC = 135°

m∠ABC = 135° - 25°

= 110°

Therefore, measure of angle ABC is 110°.
