Question

PLEASE Find the value of x?

Answer 1

Explanation:

11 + 5 = big hipo = 16

16 / x = x / 5

x*x = 16*5

x² = 80

x =
`√(80)` (do this lame calculus)

x = 4
`√(5)`

y² = (4
`√(5)`)² - 5²

y² = (4
`√(5)`) * (4
`√(5)`) - 25

y² = 16 + 4
`√(5)` + 4
`√(5)` +
`√(25)` - 25

y² = 16 + 8
`√(5)` + 5 - 25

y² = 16 + 8
`√(5)` - 20

y² = - 4 + 8
`√(5)`...

I give up..
