Question

Find CB. A 12 с 13 в

Answer 1

Answer:

25

Step-by-step 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.
