Question

Trigonometric Functions question. "What is the length of side BC? *Picture in comments*

Answer 1

This is a wonderful application of the Tangent function. What's your plan?

Answer 2

I don't necessarily have a plan. I'm completely stuck.

Answer 3

Did you miss the hint? Try the Tangent function.

Answer 4

20degrees

Answer 5

Why would the side of a triangle be measured in degrees? It's a length.

You must memorize this: Given an angle, A, and a Right Triangle, ABC, \(tan(A) = \dfrac{Opposite}{Adjacent} = \dfrac{mCB}{mAB}\).

Answer 6

I didn't mean to say degrees x''D

Answer 7

Legs are the same size in a 45-45-90 right triangle. You don't have one of those.

How did you use the tangent function?
