To find the measure of angle B in the right triangle, we can use the sine, cosine, or tangent functions. In this case, given that 15 is the adjacent side and 8 is the opposite side, we can use the tangent function:

\[
\tan(B) = \frac{\text{opposite}}{\text{adjacent}} = \frac{8}{15}
\]

To find angle B, we take the arctangent (inverse tangent) of both sides:

\[
B = \tan^{-1}\left(\frac{8}{15}\right)
\]

Using a calculator:

\[
B \approx \tan^{-1}(0.5333) \approx 28.07 \, \text{degrees}
\]

Rounding to the nearest whole number, the measure of angle B is approximately **28 degrees**.
