Question

What is the approximate value of tan C?

Answer 1

B. 0.38

Explanation:

Tan = Opposite/Adjacent

Opposite of angle C = 5 and adjacent = 13

Hence tan C = 5/13 = .38

Answer 2

Explanation:

Remark

You are given a right angle triangle, so it is possible to define the Tangent directly.

Definition

• The tangent = opposite side / adjacent side.
• The opposite side (AB) is the side not connect to the angle's vertex (C)
• The adjacent side (BC) is the side that is connect to the angle's vertex (C).
• It is not the longest side in triangle. The hypotenuse (BC) is the longest side.

Solution

Opposite Side = 5

Adjacent side = 13

Tan(C) = 5/13 = 0.3846
