Answer:
A: 65° B: 65° C: 125° D: 125°
Explanation:
It is an equilateral(shown by the two dashes) and all angles in a triangle add up to 180°.
180-50 divided by 2 to give you A and B angles.
Then angled on a straight line add up to 180° so if you take angle A away from 180° you will get the answer to angle C.
The same for angle D.
