Question

three angles of quadrilateral are 54 , 80 and 116 degree..How to find measure of the fourth angle..please do in steps

Answer 1

Hello dear



Here is your answer ______________

Let the fourth angle be X

We know that the sum of all angles of a quadrilateral = 360°

A/q
=> 54° + 80° + 116° + X = 360°
=> 250° + X = 360°
=> X = 360° - 250° = 110°

Hence,
Fourth angle = X = 110° ans.
