Question

three angles of a quadrilateral are equal. the fourth angle is twice any one of these angles. find the measure of each angle​

Answer 1

Answer:

let the three angles be x and the forth angle be 2x

Step-by-step explanation:

then,

A+B+C+D = 360

x+x+x+2x=360°

5x=360°

x=360/5

x=72

then, ANGLE A=B=C=72 and ANGLE D=72*2=144
