Question

Find CB.

Answer 1

25

Explanation:

I used Pythagoras theorem

`m {}^(2) + d {}^(2) = a {}^(2)`

I used this equation to solve the question

`x {}^(2) + 12 {}^(2) = 13 {}^(2)`

then I sold for x by doing the inverse operation or subtracting both sides by 12 to the power of 2

`x {}^(2) + 12 {}^(2) - 12 {}^(2) = 13 {}^(2) - 12 {}^(2)`

`x = 25`

if you want more info I am willing to help.
