please answer me guys please I will follow you definitely​

Answer 1

Answer:

80°

Step-by-step explanation:

let two equal angles are x° each

remaining two angles are 90° and 110°

sum of angles of quadrilateral=360°

x°+x°90°+110°=360°

2x°+200°=360°

2x= 360° - 200°

2x=160°

X=160°/2

X=80°

each equal angle= 80°
