Question

find the value of the given figure,4 .

​

Answer 1

Answer:

8

Step-by-step explanation:

In right angle triangle for sides apply Pythagoras therom

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

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

(PQ)^2=(17)^2-(15)^2

(PQ)^2=289-225

(PQ)^2=64

PQ=√64

PQ=8

Answer 2

Answer:

the answer is x= 8

Step-by-step explanation:

given that ; PR ^2 = PQ^2 + QR^2

17^2 = x^2 + 15^2

289- 225 =x^2

x^2 = 64

x = 8
