Answer 2

Answer:

40°,80°, 100°,140°

Step-by-step explanation:

Let the angles of the quadrilateral be

2x, 4x, 5x, 7x

we know that,

sum of angles of a quadrilateral = 360°

so,

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

18x = 360

x = 360/18

x = 20

so,

angles = 2(20)

= 40°

4(20)

= 80°

5(20)

= 100°

7(20)

= 140°

so,

Angles of the quadrilateral

= 40°,80°, 100°, 140°
