Question

Three angles of a quadrilateral are 54' 80 and 116 . Find measure of fourth angles

Answer 1

Let the measure of the fourth angle be x

54+ 80 + 116+ x = 360 (As the sum of angles of quadrilateral is 360)

250 + x= 360

x = 360 - 250

x = 110

Hence, the measure of the fourth angle is 110o.

Answer 2

Given :

Three angles of a quadrilateral are 54' 80 and 116 .

To find :

Find measure of fourth angles

Solution :

Sum of all angles in quadrilateral = 360

54 + 80 + 116 + x = 360

250 + x = 360

x = 360 - 250

x = 110

Therefore, The measure of fourth angle is 110°
