Question

the length of a side of a rhombus is 5 m and one of its diagonals is of length 8 m. what is the length of the other diagonal​

Answer 1

Answer:

ABCD IS RHOMBUS

BO =OD

AO =OC

ANGLE O,= 90

USING PYTHAGORAS THEOREM IN

DOC

$dc {}^{2} = oc {}^{2} + od {}^{2} \\ 5 {}^{2} = 4 {}^{2} + x {}^{2} \\ 25 = 16 + x {}^{2} \\ x {}^{2} = 25 - 16 \\ x {}^{2} = 9 \\ \sqrt{x {}^{2} } = \sqrt{9 } \\ x = 3$

so x =3

So BD = 6m
