Question

One pair of adjacent sides of a parallelogram is in the ratio 3:4.if one of its angles,angleA is aright angle and diagonal BD= 10cm,find the-

Answer 1

Step-by-step explanation:

DIAGONAL WILL BE 10cm

SIDES ARE IN RATIO 3:4

SO THE SIDES WILL BE 3x AND 4x

ONE ANGLE IS 90°

BY USING HYPOTENUSE THEORM

WE GET:

[3x]^2 + [4x]^2= [10]^2 9x^2 + 16x^2 = 100 25x^2=100 x^2= 4 x = 2

THEN SIDES OF PARALLELOGRAM ARE 3x2=6 AND 4×2=8
