Question

find the unknown length in the following figures ​

Answer 1

QUESTION1:-

Given, AB= 15 cm, CB= 8cm

Therefore, x=

x²=15²+8²[By, Pythagoras theorem]

x²=225+64

x²= 289

x= √289

x= 17

QUESTION2:-

Given, RQ=4cm, PR=5cm

Therefore, x=

x²=3²+4²[By, Pythagoras theorem]

x²=9+16

x²=25

x=√25

x=5

QUESTION3:-

Given, XY=24cm, YZ=7cm

Therefore, x=

x²=24²+7²

x²=576+49

x²=625

x=√625

x=25
