Using the law of tangents:

Tan(angle) = Opposite leg / Adjacent leg

Tan(30) = b / 8

Rewrite to solve for b:

b = 8 * tan(30)

Answer:

b = 8 * Tan 30

Step-by-step explanation:

Points to remember

Trigonometric ratio

Tan θ = Opposite side/Adjacent side

From the figure we can see that a right angled triangle ABC

Bc = 8ft, <C = 90° and <B = 30°

To find the equation of finding the b

We have,

Tan θ = Opposite side/Adjacent side

Tan 30 = AC/BC = b/8

b = 8 * Tan 30
