Question

What is the length of x?

Answer 1

The length of 'x' is 4

Explanation:

We can use the pythagorean theorem to solve this.

The pythagorean theorem is:

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

`a ^(2) + b^(2) = c^(2) \\ {3}^(2) + {b}^(2) = 5^(2) \\ 9 + {b}^(2) = 25 \\ ( - 9 \: \: \: \: \: \: \: \: = - 9)/(b ^(2) = √(16) ) \\ b = 4`

Therefore x = 4
