Answer:

[tex]BM = 14[/tex]

Step-by-step explanation:

Given

The attached triangles

Required

Find BM

We have that:

ABC is similar to JHG

This implies that:

AB corresponds to JH

BC corresponds to HG

AC corresponds to JG

BM corresponds to HN

Hence, HN can be solved using the following equivalent ratios

[tex]AB : BM = JH:HN[/tex]

From the attachment;

[tex]AB = 21; JH = 24[/tex]

So, we have:

[tex]21 : BM = 24:16[/tex]

Express as fraction

[tex]\frac{21 }{ BM }= \frac{24}{16}[/tex]

Cross multiply

[tex]BM * 24 = 21 * 16[/tex]

[tex]BM * 24 = 336[/tex]

Solve for BM

[tex]BM = 336/24[/tex]

[tex]BM = 14[/tex]
