Question

one angle of a quadrilateralis lll. and the remainingangles are equal. find three angles?​

Answer 1

Answer:

Given, one angle = 111 degree

Let the othet angle be X degree

total angle of quadrilateral = 360 degree (by angle sum property of a quadrilateral)

therefore 111+X+X+X=360

111+3X= 360

3X=360-111

3X=249

X=249/3

X=83
