Which equation can be used to solve for b?

Using the law of tangents:

Tan(angle) = Opposite leg / Adjacent leg

Tan(30) = b / 8

Rewrite to solve for b:

b = 8 * tan(30)

The first answer is correct.

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

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
