The trig functions & right triangle trig ratios - Khan Academy
Trigonometric Tables: Before the advent of calculators, trigonometric tables were widely used to look up values of trigonometric functions for specific angles. These tables provide precomputed values for common angles, and you can interpolate between values for angles that are not listed.

At what angle should the agent shoot his laser gun? Round your answer, if necessary, to two decimal places. So if we construct a right triangle here, and we can. So the height of this right triangle is 324 meters. This width right over here is 54 meters. It is a right triangle. What they're really asking us is what is this angle right over here.
Unit 1: Right triangles & trigonometry - Khan Academy
Can you find the length of a missing side of a right triangle? You most likely can: if you are given two side lengths you can use the Pythagorean Theorem to find the third one. But, what if you are only given one side? Impossible? Cue sine, cosine, and tangent, which will help you solve for any side or any angle of a right triangle.
Non-right triangles & trigonometry | Math | Khan Academy
In this unit, you will discover how to apply the sine, cosine, and tangent ratios, along with the laws of sines and cosines, to find all of the side lengths and all of the angle measures in any triangle with confidence.
