You can put this solution on YOUR website! Consider △ABC, where AB=AC=13 units, and m∠BAC=80°. What are the measures of ∠ABC and ∠ACB?
m∠ABC=__________° and m∠ACD=__________°.
-------------
You have an isosceles triangle.
The vertex angle is 80 deg.
The 2 base angles are opposite equal sides and therefore equal.
------
Each of the base angles is (180-80)/2 = 50 degrees
m∠ABC= 50° and m∠ACD= 50°.
