Question

One angle of a quadrilateral is 180 and the remaining angles are equal. Find the three equal angles

Answer 1

sum of the anglesof a qudrilateral=360degrees
one of its angle =180 And rest three are equal
So the angles Are 180,x,x,x
And 180+x+x+x=360
180+3x=360
3x=360-180
3x=180
x=180/3
x=60
so the angles are 180,60,60,60

Answer 2

let the 3 equal angles b x .x+x+x+180=360(sum of angles of a quadilateral)
3x=180
x=60
