Question

An exterior angle of a triangles is 15° and it's two interior opposite angles are equal. Each of these equal angle is​

Answer 1

Step-by-step explanation:

If one exterior angle is 110, then opposite interior angle to it is of (180-110=70°

Then,

Let the other two equal interior angles be x and x, then

x+x+70=180

2×=180-70

2×=110

x=55

All interior angles are 55,55,70
