Question

Measure of ∠A= __________, Measure of ∠B = __________,

Sum (∠A + ∠B) = ________, Measure of ∠ACD = _______.

Therefore, ∠ACD = ∠A + ∠B.​

Answer 1

Given :-

Measure of ∠A= __________, Measure of ∠B = __________,

Sum (∠A + ∠B) = ________, Measure of ∠ACD = _______.

Therefore, ∠ACD = ∠A + ∠B.

Answer :-)

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Hence, In this case ∠A and ∠B

So,

∠A+∠B=140°

as ∠A=∠B

or,2∠A=140°

∠A=∠B=70°
