Question

In triangle ABC,angle B=90° and angle BD perpendicular AC. If DC=7cm and AD=3cm find the length of BD.

Answer 1

it is the answer of the problem and I hope it helps you

Answer 2

Answer: The length of BD = 5 cm.

Step-by-step explanation:

Since we have given that

ABC is the right angled triangle, in which ∠B = 90°

DC = 7 cm

AD = 3  cm

So, AC = AD + DC = 7 + 3 =10 cm

Since, BD is perpendicular to AC.

As we know that Length of BD is the half the length of hypotenuse.

So, the length of BD is given by

$\dfrac{10}{2}=5\ cm$

Hence, the length of BD = 5 cm.
