Question

Two angles of a quadrilateral are 68° and 76°. If the other two angles are in the ratio 5 : 7; find the measure of each of them

Answer 1

Step-by-step explanation:

Sum of all angles of quadrilateral= 360 deg.

Lets take other two angles as 5x and 7x

5x+7x+68+76=360

12x+144=360

12x=360-144

12x=216

x=216/12= 18 deg.

So angles of quadrilateral are 90º,126º,76º,68º
