Question

ANYBODY KNOW THIS????

Answer 1

The length of BD equals 7.4

Explanation:

We can use the pythagorean theorem to solve this.

This is the pythagorean theorem:

`{a}^(2) + {b}^(2) = {c}^(2)`

Let's solve.

`{a}^(2) + {b}^(2) = {c}^(2) \\ {a}^(2) + {3}^(2) = {8}^(2) \\ {a}^(2) + {9} = {64} \\ \frac{ \: \: \: \: \: \: - 9 = - 9}{ {a}^(2) = √(55) } \\ a = 7.4`

Therefore, The length of BD = 7.4.
