Question

find the unknown length x in this figure​

Answer 1

Answer:

Step-by-step explanation:

by using Pythagoras theorem

in Triangle ADC

AC²= DC²+AD²

25²= 24²+DC²

DC²=25²-24²=49

DC=7

Then BD=10cm

In Triangle ADB

AB²= BD²+AD²

x²=10²+24²=100+576

x²=676

x=26

Answer 2

Answer:

first find the length of DC

by the phythagorous theorem of triangle ADC

AD² + DC²=AC²

24²+ DC²=25²

576+DC²=625

DC²=625-576

DC²=49

DC=7 m

BD+DC=BC

BD+7=17

BD=17-7

BD=10m

now take triangle ABD

AB²=BD²+AD²

X²=10²+24²

X²=100+576

X²=676

X=26m
