Question

The side of rhombus is 13 cm and the length of one of the diagonal is 24 cm . Find the length of the other diagnal

Answer 1

let's see it is a rhombus ABCD let a be the midpoint of line segment AC and line segment BD therefore Midpoint of AO=1/2AC=12cm.In triangle AOD,m/_O

=90 therefore AD2= AO2+OD2 therefore 169 - 144 = OD2 thereforeOD = 5 cm therefore BD = 2OD also equal to 10 cm therefore BD is equal to 10 centimetre.
