Question

one of the exterior angles of triangle is hundred degree the interior opposite angles are equal to each other find the measure of these equal interior opposite angles​

Answer 1

Answer:50° each

Step-by-step explanation:

Let the 1st interior angel be x

Both angles are equal. So 2nd angle also be x

Exterior angle=100°

As we know, exterior angle= sum of two interior opposite angle

x+x=100°

2x=100°

x=100°/2

x=50° Answer

Answer 2

Answer:

50°

Step-by-step explanation:

Let the interior opposite angles be x

Exterior angle = 100°

According to exterior angle property of a triangle :

$\implies$ $x+x=100°$

$\implies$ $2x=100°$

$\implies$$x=\Large\frac{100}{2}$

$\implies$ $\boxed{x=50°}$
