Please help thank you.

Answer 1

Hello!

First you have to find BO

BC = 27
AO = CO
CO = 24

BO = 27 + 24

BO = 51

Now we use the Pythagorean Theorem

24^2 + b^2 = 51^2

Square the numbers

576 + b^2 = 2601

Subtract 576 from both sides

b^2 = 2025

Take the square root

b = 45

The answer is A) 45

Hope this helps!
