Question

One of the quadrilateral is 108 degree and other three angles are equal ,then the value of each angle angle is _______

Answer 1

let the other equal angles be X.
108 + x +x +x = 360 (angle sum property of quadrilateral)
108 + 3x = 360
3x = 360 - 108
x = 252/3
x = 84 degree ans.

Answer 2

let the other angles be x
x+x+x+108=360
3x+108=360
3x=360-108
3x=252
x =252/3
x =84
therefore other angles are 84,84,84
hope it helps
