Question

an exterior angle of a triangle is 105 degree and its opposite two
interior angles are equal what will be the measurement of each of these angles

Answer 1

both angles will be 52.5 deg as exterior angle is equal to the sum of both the interior opposite angles

Answer 2

Answer: Exterior angle =105

So angle 1 =180-105

I.e =75

So angle 1+angle2+angle3 =180

We were given that two opposite angles are equal so we take angle 1=angle2

i.e 75+75+angle 3 =180

=150+angle 3=180

So angle 3= 30
