Question

1. Two angles of a quadrilateral are 89° and
113°. If the other two angles are equal, find the
equal angles.​

Answer 1

Step-by-step explanation:

let equal angles be x

we know,sum of angles of quadrilateral=360°

therefore,89+113+x+x=360°

202°+2x=360°

x=158/2

x=79

so, equal angles are 79°each

Answer 2

Answer:

Let the equal angles be=x°

Angle sum of a quadrilateral=360°

=> x°+x°+113°+89°=360°

2x°+202°=360°

2x°=360°-202°

x=158/2

x=79°
