Question

Angle a and angle d of a paralleogram are in the ration 1:3.What is the greatest angle of a palleogram

Answer 1

sum of the parallelogram angle =180

ratio of parallelogram =1:3

let first angle =1x

second angle =3x

1x+3x=180

4x=180

x=180/4

x=45

therefore,

required angles are

first angle =1x=1*45=45

second angle =3x=3*45=215
