Answer 1

question a. let the angles of quadrilateral be x , 2x ,3x,4x

x+ 2x + 3x +4x = 360degree ( sum of the angles of quad.)

10x = 360°

x = 360÷ 10

x = 36

2x = 2×36 = 72°

3x =3×36=108°

4x= 4×36=144°

Answer 2

Answer:

A) Let first angle = x

second angle = 2x

third angle = 3x

forth angle = 4x

In quadrilatreal,

x+2x+3x+4x = 360

10x = 360

x = 360/10

x = 36

first angle = x = 36

second angle = 2x = 2× 36 = 72

third angle = 3x = 3 × 36 = 108

forth angle = 4x = 4 × 36 = 144
