Question

Find the measure of angle ABC in the figure given above if angle A = 70° and angle ACD = 120° (answer will be brainlisted if it helped me)
​

Answer 1

Answer:

An exterior angle is equal to the sum of measure of interior angles.

hence,

angle A + angle B = exterior angle

70⁰ + angle B = 120⁰

angle B = 120⁰ - 70⁰

angle B = 50⁰

ABC = 50⁰
