Question

I really need help please!!

Answer 1

Using similar triangles, we see that 12/x = x/16. Multiplying by 16x, we see that x^2=12*16=192.

By the Pythagorean Theorem,
`12^2+y^2=x^2`. Since x^2=192, we know that
`144+y^2=192`. Subtracting 144 from both sides, we see that
`y^2=48`, so y=
`4 √(3)`.
