Question

If an angle of parallelogram is 4/5th of its adjacent angles .What is the smaller angle of parallelogram.​

Answer 1

let the one angle be x

now, other angle would be 4/5 of x

since they are adjacent angles of ||gm and we know they are supplement

thus,

x + 4/5*x = 180

9x/5 = 180

x = 180*5/9

x = 100

and other angle = 80
