Question

three angles of a quadrilaterals are equal,forth angles is a rigth . find the measures of the angles​

Answer 1

Answer:

The three angles are equal, let each be equal to x. Therefore the sum of the three angles is 3x. x = 90 degrees

Answer 2

Answer:

Given-

Three angles of quadrilateral are equal, then let the angles be x

The fourth angle is right angle i. e. 90°.

We know that,

Sum of all angles of quadrilateral =360°

AngleA+AngleB +AngleC +AngleD=360°

X + X + X +90°=360°

3X=360°-90°

X=270°÷3

X=90°

Hence all the angles of the quadrilateral are 90°
