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°
