WebJan 17, 2014 · Sine, cosine, and tangent. With all of these preliminaries now happily splashing around inside our growing pool of mathematical knowledge, we’re finally ready to tackle the meaning of sine, cosine, and tangent. Here’s the key idea: The ratios of the sides of a right triangle are completely determined by its angles. WebThe sides of the right triangle are referenced as follows: Adjacent: the side next to θ that is not the hypotenuse; Opposite: the side opposite θ. Hypotenuse: the longest side of the triangle opposite the right angle. The other two most commonly used trigonometric functions are cosine and sine, and they are defined as follows: Tangent is ...
WebAnswer: I assume the 30 cm is the two, equal sides adjacent to the 35° angle. A few ways to proceed depending on what you want to solve for. 1. If you only want the remaining side, law of cosines is the direct approach. But also consider #3. 2. The more general approach if you plan to completely...
