Question

In the figure, find PR and QR​

Answer 1

Answer:

according to Pythagoras theory 7^2+12^2=13^2 so the answer will be x=12 and ×+1=13

Answer 2

Step-by-step explanation:

In the right angle triangle,∆PQR

By Pythagoras theorem,

(PR)^2 = (PQ)^2 + ( QR)^2

(x+1)^2 = 7^2 + x^2

x^2 + 1 + 2x = 49 + x^2

2x = 49 -1

2x = 48

x = 48 /2

x = 24

now,

PR = x +1

= 24 +1

= 25

QR = x

= 24....

hope this helps you....
