Answer 1

may be this helps u.

Answer 2

let the first angle be 2x
second angle be 4x
third angle be 5x
fourth angle be 7x

sum of all the angles of a quadrilateral is 360°

2x+4x+5x+7x=360°
6x+12x=360°
18x=360°
x=360°/18
x=20°

so,
first angle=2x=2*20=40°
second angle=4x=4*20=80°
third angle=5x=5*20=100°
fourth angle=7x=7*20=140°

hope it helps you
