Question

in the right angled triangle pqr shown below pq=11.9cm and qr=5.6cm calculate the length PR

Answer 1

Answer:

10.5cm

Step-by-step explanation:

In triangle PQR,

by using Pythagoras theorem

PQ^2 = PR^2 + QR^2

(11.9)^2 = PR^2 +(5.6)^2

PR^2 = 141.61 - 31.36

PR^2 = 110.25

PR = 10.5cm
