the length of each side of the rhombus pqrs is 15cm if diagonal pr=24cm find the length of the other diagonal qs Share with your friends Share 3 Manbar Singh answered this We have, PQRS as the given rhombus, inwhich diagonals PR and QS intersect at O.Now, we know that diagonals of rhombus bisect each other at right angles, then∠POQ = ∠QOR = ∠ROS = ∠SOP = 90°and OP = OR = PR2 = 242 = 12 cmOS = QQ = QS2Now, In ∆POQ,PQ2 = OP2 + OQ2 Pythagoras theorem⇒ OQ2 = 152 - 122 ⇒ OQ2 = 225 - 144⇒OQ2 =81⇒OQ = 9 cmNow, QS = 2OQ = 18 cm 11 View Full Answer
