Question

Geometry help PLEASE

Answer 1

solve for x, first

8^2 = x * 15
solve for x

Answer 2

I got 64/15

Answer 3

yes, x = 64/15

Answer 4

then see the triangle of BCD, use the pythagorean theorem :
y^2 = x^2 + 8^2

we got x = 64/15, so
y^2 = x^2 + 8^2
y^2 = (64/15)^2 + 8^2
solve for y

Answer 5

136/15

Answer 6

what about the second one?
