Question

one angle of a quadrilateral is of 108 degree and the remaing three angles are equal. find each of three equal angles

Answer 1

We know that the sum of all angles of a quadrilateral = 360°

Measure of 1 angle = 108°

The rest 3 angles are equal so let their measure be 'x°'

=>  3x = 360 - 108

=> 3x = 252°

=> x = $\frac{252}{3}$

=> x = 84°
