Question

one angle of a quadrilateral is 150 degrees and the other 3 are equal.what is the measure of each of these equal angles​

Answer 1

Explanation:

We know sum of all angles of a quadrilateral is 360 degree

Measure of one angle of the quadrilateral =150 degrees
Assume the remains three equal angles as x

Therefore, 150 + x + x + x=360
150 + 3x=360
3x=360- 150
3x=210
X=70

Ans) the measure of each angles of the quadrilateral is 150, 70, 70, 70 respectively
