Question

three angles of quadrilateral are 110 ,88 and 92 degree respectively find the fourth angle

Answer 1

First angle = 110°

Second angle = 88°

Third angle = 92°

By angle sum property of quadrilateral,

First angle + Second angle + Third angle + Fourth angle = 360

=> 110 + 88 + 92 + Fourth angle = 360°

=> 290 + Fourth angle = 360

=> Fourth angle = 360 - 290

=> Fourth angle = 70°

Answer 2

As we know that sum of  the angles of a quadrilateral is 360

Hence,

360 = 110 + 88 + 92 + fourth angle

360 = 198 + 92 + fourth angle

360 =290 +fourth angle


360- 290 = fourth angle

70 = fourth angle


i hope this will help you
