Question

one angle of a quadrilateral is 180 degree and the remaining three angles are equal find each of three equal angles

Answer 1

here is the answer.....

Answer 2

Let the equal three Angles be x
Then, x+x+x+180 =360
3x+180=360
3x =360-180
3x=180
x=180/3
x=60
So all the three equal angels are 60 degree
