Question

an exterior angle of a triangle is 130 degree and the two interior opposite angles are equal find each interior opposite angle

Answer 1

130=x+x
=2x
x=65 interior angle

Answer 2

Hey!


Let the two equal interior angles be X °

Exterior Angle = 130°

Now , Using the Exterior Angle Property ,

✨Exterior Angle of Triangle Is equal to the Sum of opposite interior angles ✨
-----------------------------------------------------------------------------------------------------


X + X = 130

2X = 130

X = 130/2

X = 65°


➡Hence the measure of the equal interior angles is 65°
