Question

✳✳✳✳✳✳✳✳✳✳✳✳✳✳✳
If the adjacent angle of a parallelogram are in the ratio 2:3 and the sum of all the sides is 50 cm , find the measure of the side of the parallelogram...❗❗❗

Answer 1

as adjacent angles are in 2:3 ratio

so let it be 2x and 3x

therefore the other two  angles must 3x and 2x

sum of all angles=360

10x=360

x=36

therefore the angles are 72,108,72,108

after this maybe we have to use trigonometry and also the information that 2A+2B=50

A+B=25

plz tell me from which class is this question
