Question

6) ACD is an exterior angle of AABC mZACD = 140 m ABC =80° Find a) m ZACB B D b) m BAC​

Answer 1

Answer

Answer Is 70 degree

Step-by-step explanation:

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
