Answer:

b=(8)tan(30\°)

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC, the tangent of angle of 30 degrees is equal to divide the opposite side to the angle of 30 degrees (AC) by the adjacent side to the angle of 30 degrees (BC)

tan(30\°)=AC/BC

substitute the given values

tan(30\°)=b/8

Solve for b

b=(8)tan(30\°)
