Question

one of the exterior angle of a triangle is 100 degree and its interior opposite angles are equal to each other. what is the measure of these two angles ? answer in process

Answer 1

Sum of interior opposite angles=exterior angle of a triangle
=>let interior angle=x
=>2x=100°
=>x=50°

Answer 2

the answer will be 50°
Because the sum of two interior angles is equal to the opposite exterior angle so
let the interior angle be = x
then
$2x = 100 {}^{0}$
$x = 50 {}^{0}$
here you go
have a nice day.
