Question

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

Answer 1

Answer:

Step-by-step explanation:

The remaining angle sum=360-144=216

The angles are 5/12×216=90

Other is 7/12×216=126

Answer 2

angle sum property of a quad is=360°

68°+76°+a+b=360°

144°+a+b=360°

a+b=216°

a=(5/12)*216

a=90°

b=(7/12)*216

b=216°
