Question

find each angle of parallelogram if two consecutive angels are in ratio 1 : 3

Answer 1

as we know that the parallelogram has two equal angles,

then 

then let ratio be x and 3x 

x+3x+x+3x = 360

8x= 360

x= 360/8

x=45

then then angles are :-

45 
45*3 = 135
45 
3*45= 135


i hope this will help you

Answer 2

let the common multiple be x
then the consecutive angle will be 1x and 2 x
we know that measure of all angles of parallelogram is 360 and also sum of adjacent side is 180...
by the help of this u can calculate the angles..
this was a small hint... hope this helps u
