Answer:

b=(8) tan (30°)

Step-by-step explanation:

We can use trigonometric ratios to solve a right triangle if the length of one side and an acute angle is known.

In the provided figure the side b is opposite the acute angle BCA while a is adjacent.

Therefore we can use the tangent to find the value of b.

Tan 30 =b/a  

Tan 30 =b/8ft

b=(8) tan 30°

Answer:

A. (8)tan(30)
