Multi-Step Trig Problems Since they're really acing the introductory trig material, I am ramping my honors kids up to laws of sines and cosines. To do that, I am going to make them divide* scalene triangles into smaller right triangles, in order to really understand side and angle relationships within general scalene triangles.

The fields that trigonometry is being used today for include electronics, engineering, and calculus. A study of trigonometry will primarily involve concepts of angles, the right triangle, and the unit circle. The problems you can solve with trigonometry are many. A short list includes the following: Angle of elevation. Angle of depression Physics problems sometimes require you to have some trigonometry under your belt. To see what kind of trig you need, take a look at the figure, which shows a right triangle. The long side is called the hypotenuse, and the angle between x and y is 90 degrees. Physics problems require you to be able […]

In old grammars they paid much more attention to word groups than to sentences. Still later the term "phrase" was introduced for...
master problem solving one needs a tremendous amount of practice doing problems. The more problems you do the better you will be at doing them, as patterns will start to emerge in both the problems and in successful approaches to them. You will learn fastest and best if you devote some time to doing problems every day.

Answer Explanation: Similarly to the other trigonometry problem, there are two ways to solve this problem. The quicker way is to realize that x and y are complementary angles (add up to 90°). Then, using the complementary angle relationship for sine and cosine, which is $\sin(x°)=\cos(90°−x°)$, you realize that $\cos(y°)=0.6$.
Trigonometry Help at Math-Mate Tutorials for basic trig topics, such as: naming the sides of a right triangle, ratios between the side lengths, using trigonometry to work out side lengths, trigonometry on the calculator, using Pythagoras' Theorem, application problems in trigonometry.
Solving a right triangle can be accomplished by using the definitions of the trigonometric functions and the Pythagorean Theorem. This process is called solving a right triangle. Being able to solve a right triangle is useful in solving a variety of real-world problems such as the construction of a wheelchair ramp.
