Question

The sum of three angles of a quadrilateral is 250°.find the measure of fourth angle

Answer 1

Given,

Sum of three angles in quadrilateral = 250

let the fourth angle be x

Sum of all angles in Quadrilateral = 360

ATP,

x + 250 = 360

x = 360 - 250

x = 110

Answer 2

sum of three angles = 250°
Measure of quadrilateral= 360°
360-250=110
fourth angle=110°
