Question

Pls help thxx!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

y ≈ 10,7

Explanation:

I added a photo below

First, let's find x by using the Pythagorean theorem from ∆CBD:

`{x}^(2) = {8}^(2) + {6}^(2) = 64 + 36 = 100`

`x > 0`

`x = √(100) = 10`

Now, we can find AC by using the Pythagorean theorem from ∆ACD:

ac = y^2 + 64

ac > 0

ac = sqrt (y^2 + 64)

Now from the triangle ACB make an equation as I did in my second photo.
