Question

An exterior angle of a triangle is 110° degree and its two interior opposite angles are equal find each of these equal angles

Answer 1

Let the interior angle = x

The second one is equal so that also = x

Now ,
x + x = 110°

2x = 110°

x = 110° /2

x = 55°

The each of the equal angles is of 55° .

Answer 2

here is your solution

we know that:-

sum of two interior opposite angle =exterior angle

let equal angle be x

a/q

x+x=110°
2x=110°

x=55°

Hence
equal angle be 55°
