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...
Learn how to find the missing sides or angles of a right triangle when one length and one angle are provided.
How to find the length of the hypotenuse of a right triangle with only one leg length and all angle measurement? Right Triangle: The right triangle is a type of triangle in which there are two angles are acute and one right angle. The ratio of...
Step 2:Use definitions to find the remaining trigonometric functions. Definitions and Formulas for Finding the Values of Trigonometric Functions & their Reciprocals Standard Trigonometric Functions:A function that takes an input of an angle, and returns a ratio of side lengths of the associat...

The sine of an angle is given by the quotient between the opposite side and the hypotenuse of a right triangle. This quotient, as well as other types of quotients, are known as trigonometric ratios. These trigonometric ratios are basic tools used in trigonometry to study right triangles, ...
meters long and goes down at an angle of 36°. Now we can calculate how much vertical and horizontal space this slide will take. We are basically in the same triangle again, but now we know theta is 36° and r = 4. Then to find the horizontal length x we can use the cosine. We...
The area of a scalene triangle with base b and height h is given by 1/2 _bh_. If you know the lengths of all three sides, you can calculate the area using Heron's Formula without having to find the height. If you know the value of an angle and the lengths of the two ...
Here, the adjacent side is adjacent to angle x, and the hypotenuse is the triangle’s longest side. Students can find the detailed explanation below. Cos 120°: ValueIn order to find the value of cos 120°, students need to draw a right-angled triangle (refer to the image below) and ...
Trigonometric Functions:A function that takes an input of an angle and returns the ratio of side lengths for the right triangle. The basic functions are {eq}\sin(x) {/eq}, {eq}\cos(x) {/eq}, and {eq}\tan(x) {/eq}. SOH-CAH-TOA:An acronym used to help remembe...
