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:
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
