When you choose which of the two angles (ø) in a right triangle you want to find, you establish three sides in relation to it. The line that touches the angle and extends to the 90-degree angle is called the adjacent side, while the side opposite the angle is the opposi...

Sine, cosine and tangent, often shortened to sin, cos, and tan in mathematical operations and on calculator keys, are the most basic trigonometric functions. All three are based on the properties of a triangle with a 90-degree angle, also known as a right triangle. By knowing the sides of...
Since sin 43° is being divided by a, we'll multiply both sides by that. And we'll use our calculator to find the length of side a: a ≈8.3 m. 2. Find the measure of angle C. We cannot use the Law of Sines to find the measure of angle C, but we can use the fact that ...
Divide the sine of the known angle in both triangles by the length of the opposing side. For example if you have a two triangles with a angle of 20 degrees and an opposing side of 10 inside a quadrilateral, you would get a quotient of 0.03 (sin20 / 10 = 0.03). ...
If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle. If you have the non-hypotenuse side adjacent to the angle, divide it by cos(θ) to get...
