Question

Use the geometric mean (altitude) theorem. What is the
value of m?
27
4710
m
20
160
8

Answer 1

Answer:

4√10 ( option C)

$solution \\ from \: the \: geometric \: mean \: therem \\ \frac{8}{m} = \frac{m}{20} \\ or m \times m = 20 \times 8 \\ or \: {m}^{2} = 180 \\ or \: m = \sqrt{180} \\ m = 4 \sqrt{10}$

Hope this helps...
