Answer:

b=6

Step-by-step explanation:

One of the kinds special triangles you learn about are the Pythagorean triples.  These are right triangles with sides in certain ratios. One of them has sides in the ratios 3:4:5.

More generally, this triangle has sides in the ratio 3x:4x:5x

In your triangle, the ratio 8:10 corresponds to 4x:5x with x=2.  Therefore, the remaining side is 3x with x=2, so

b=6
