Question

the angles of a quadrilateral are in the ratio 1:2:4:5 find all the angles of the quadrilateral
​

Answer 1

Answer:

x+2x+3x+4x+5x = 360 then 12x=360

X=360÷12

Explanation:

x=30

2x=60

4x=120

5x =150

Answer 2

Answer:

30° ,60° , 120° ,150°

Explanation:

Let the angles of the quadrilateral be 1x,2x,4x,5x

As sum of angles of a quadrilateral is 360°

then, 1x + 2x+ 4x+ 5x= 360°

12x= 360°

x= 30°

Hence, angles of the quadrilateral measures

1x = 30°

2x = 60°

4x = 120°

5x = 150°
