Question

In any parallelogram , the ratio of 2 adjacent angles is 1 : 5 then find the value of all angles of parallelogram

Answer 1

Answer: In parallelogram opposite angles are equal so,

Sum of ratio = 1+5+1+5 = 12

First angle = 1/12*360 = 30

Second angle = 5/12*360 = 150

Third angle = 1/12*360 = 30

Forth angle = 5/12*360 = 150

30+150+30+150 =360

Hence, the angles of parallelogram are 30, 150, 30, 150.
