In the figure, if QR-24m, NR 4m and MN 6m, then the length of PQ is
Answers
Given:
if QR =24 m, NR = 4 m and MN = 6 m. then find the length of PQ.
To find:
The length of PQ.
Solution:
In Δ RNM and Δ RQP, we get
∠MRN = ∠PRQ . . . [common angle]
∠RNM = ∠RQP = 90° . . . [from the figure]
∴ Δ RNM ~ Δ RQP . . . [by AA similarity]
We know that →
The corresponding sides of the similar triangles are proportional to each other.
So, based on the above theorem, for the two similar triangles ΔRNM and Δ RQP, we get
on substituting the given values of QR =24 m, NR = 4 m and MN = 6 m, we get
Thus, the length of PQ is → 36 m.
