Question

Exterior angle of a triangle is 110 and its interior opposite angles are equal.Then the measure of interior opposite angle is​

Answer 1

$\Huge{\red{\underline{\textsf{ANSWER}}}}$

★ 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
