Question

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

Answer 1

Answer:

C. $y = 3\sqrt{7}$

Step-by-step 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 => $y = \sqrt{9*7}$

Thus, solve for y.

$y = \sqrt{9} * \sqrt{7}$

$y = 3\sqrt{7}$

The answer is C. $y = 3\sqrt{7}$
