Answer 1

Answer:

40, 80, 100, 140

Step-by-step explanation:

let the angle x

sum of angles

2x+4x+5x+7x= 360

18x=360

x= 20

put value of x then,

40, 80, 100, 140

Answer 2

Answer:

40°, 80°, 100°, 140°

Step-by-step explanation:

Let the angle be x

Sum of angles of a quadrilateral = 360°

2x + 4x + 5x + 7x = 360°

18x = 360°

x = 360 / 18

= 20°

Angle 1 = 20 × 2 = 40°

Angle 2 = 20 × 4 = 80°

Angle 3 = 20 × 5 = 100°

Angle 4 = 20 × 7 = 140°
