Question

"Three angles of a quadrilateral are54° , 80° and 116° . Find the measure of fourth angle. "

Answer 1

Answer:

"110°

Step-by-step explanation:

Let the measure of forth angle be x

Sum of angles of a quadrilateral = 360°

therefore, 54 + 80 + 116 + x = 360

=> 250 + x = 360

=> x = 360 - 250 = 110

hence, the measure of the forth angle is 110°"
