In Ch. 4 we learned about the 6 trigonometric functions. They arose from ratios formed within a right triangle. There's sine, cosine, tangent, cosecant, secant, and cotangent. We could use these functions to find missing angles, height, distance, length, and even the hypotenuse. The type of problem I made up was an indirect measurement. I solved the problem by using the trigonometric functions I learned from Ch. 4.
