Question

adjacent angles of a parallelogram are in the ratio 3:5 and perimeter is 120 m .find all the parallelogram.
please do it fast i will mark u as brainlist

Answer 1

hey mate!

firstly, adjacent angles of parallelogram are supplementary and opposite angles of parallelogram are equal.

so, let the angle be 3x and 5x

so, 3x + 5x = 180 degree because adjacent angles are supplementary

8x = 180

x = 180/8 = 22.5 degree

perimeter = 120 cm

so first angle is 3x = 3 × 22.5 = 67.5 degree

and second angle = 5x = 5 × 22.5 = 112.5 degree

now opposite angles are same so other two angles are also same

hope this helps you
