Question

Use the geometric mean theorems to find AC and BD. BA=20 BC=15

Answer 1

Step-by-step explanation:

first, you use the pythagorean theorem to find the missing side of the original and big triangle.

$20 {}^{2} + 15 {}^{2}$

next, you simplify these into actual numbers

$400 + 225$

after, you add these numbers together and find the square root.

$\sqrt{625} = 25$

you have the answer for AC. next you need to find BD. of you line up BC with BD, BC would be longer, , so you know its shorter, but not by much, so I'd assume to guess like 13 for BD- that's just me- but I'm not sure how to exactly find it.
