Question

3 angles of a quadrilateral are 45,60,90 find the other

Answer 1

Answer:

45+60+90+X=360

195+X=360

X=360-195

X=165

The measure of the another angle is 165 degree

Answer 2

Angle sum property of a quadrilateral states that all the 4 angles sum up to 360 degrees so the unknown angle is 360° - (45°+60°+90°) = 165 °
