Question

Three angles of a quadrilateral are 68,74,108 find the fourth angle

Answer 1

Sum of angles of a quadrilateral = 360°

Let the fourth angle be x.

68+74+108+x = 360°

250 + x = 360°

x = 110°

Hope it helps..

Answer 2

answer: fourth angle be 'x'

=> 68+74+108+x=360 (sum of angles of quadrilateral is 360°)

=> 250+x=360

=> x=360-250

=> x=110°

Therefore,fourth angle is 110°
