Question

PLEASE HELP!!
Solve for y
a) 8
b) 12
c) 3V7
d) 4V7

Answer 1

C.
`y = 3√(7)`

Explanation:

Based on the right triangle altitude theorem, the altitude, y, in the diagram above, equals the geometric mean of 9 and 7.

This implies =>
`y = √(9*7)`

Thus, solve for y.

`y = √(9) * √(7)`

`y = 3√(7)`

The answer is C.
`y = 3√(7)`
