Answer 1

Answer:

I hope you understand this answer

Answer 2

Answer:

80°,60°,140°,80°

Step-by-step explanation:

Sum of all angles of a quadrilateral is 360°

Therefore,

2x+x+20+2x+60+2x=360

7x+80=360

7x=360-80

7x=280

x=280÷7

x=40

2x=2×40=80°

x+20=40+20=60°

2x+60=2×40+60=140°

2x=2×40=80°

Therefore, the angles are 80°,60°,140° and 80°
