Using the following triangle, what is the cotangent of angle a?

The cotangent of an angle is the length of the adjacent side divided by the length of the opposite side.  Cot A = b/a

Step-by-step explanation:

The adjacent side to angle A will be side b.

The opposite side to angle A is side a.

cot A is equal to the length of the adjacent side divided by the length of the opposite side, therefore the answer is cot A = b/a

Part A: Total cost = 10 + 4s

Part B: Solving for s = 2

10 + 4 * 2 = US$ 18

Correct statement and question:

Write an expression to represent admission to a zoo of $10.00 and the cost of special exhibits s at $4 each. Evaluate your expression when s = 2.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Admission to the zoo = US$ 10

Special exhibit cost (s) = US$ 4

2. Evaluate your expression when s = 2

Total cost = Cost of admission + (s) * Special exhibit cost

Total cost = 10 + (s) * 4

Total cost = 10 + 4s

3. Solving for s = 2

10 + 4s

10 + 4 * 2 = US$ 18
