Question

Use the geometric mean (altitude) theorem. What is the
value of m?
4
2/7
4/10
160

Answer 1

Answer:

$\red{ \bold{ m = 4 \sqrt{10}}}$

Step-by-step explanation:

By geometric mean theorem:

$m = \sqrt{8 \times 20} \\ \\ m = \sqrt{160} \\ \\ m = \sqrt{16 \times 10} \\ \\ m = \sqrt{ {4}^{2} \times 10} \\ \\\huge \red{ \bold{ m = 4 \sqrt{10}}}$
