An exterior angle of a triangle is 110 degree and its two interior opposite angles are equal. Find each of these equal angles
Answered by admin @
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
2x=180-70
2x=110
x=55
All interior angles are 55,55,70
