Question

an exterior angle is measure 75 and one of its interior opposite angle measure is 25 find the measure of other interior opposite angle

Answer 1

as exterior angle is 75° and one of interior angle 25° so we know the property i.e
let angle A be 25° one of the interior angle
let angle B be another interior angle
Let angle C be 75° exterior angle

So by property of exterior angle theorm
Angle A + Angle B = Angle C
therefore 25° + Angle B = 75°
Angle B = 75° - 25°
= 50°
therefore another interior angle measure is 50°
