Answer:
BD = 14 cm
Step-by-step explanation:
In triangle ABC,
BC= √(AC^2-AB^2)
= √(169-144)
=√25
=5 cm
In triangle EDC,
DC=√(CE^2-DE^2)
=√(225-144)
=√81
=9 cm
Therefore, BD = BC+DC
=(5+9) cm
=14 cm

Answer:
BD= 14cm
Step-by-step explanation:
Hey buddy......
You should first find BC & CD so,
that u add them and find BD so,let's solve this problem.
In ∆ABC,
angle B is 90°
By Pythagoras Theorem.
AC^2=AB^2+BC^2
169-144=BC^2
BC=5 cm
In ∆CDE,
angle D is 90°
By Pythagoras Theorem.
CE^2=CD^2+DE^2
225 - 144 = CD^2
CD^2 = 81
CD= 9
BD = BC + CD
BD= 5+9=14
BD= 14cm
Hope it helps you
