Question

the angles of a quardrilateral are in the ratio 1:2:4:5 find the angles.
please show steps.

Answer 1

The angles sum to 360, divide in 12, then 1/12,2/12,4/12.....

Answer 2

it can be done like this
first add all the numbers 1+2+4+5=12
now each angle
1*360/12
2*360/12
4*360/12
5*360/12
hence the angles are
30,60,120,150

Answer 3

1+2+4+5=12
360/12= 1 in the ratio
So if 1=30 degrees then each number is each angle respectively.
