Cos Alpha Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cos Alpha = Adjacent Side of Angle Alpha/Hypotenuse Side
cos α = S_Adjacent/S_Hypotenuse
This formula uses 3 Variables

Variables Used

Cos Alpha - Cos Alpha is the value of the trigonometric cosine function of the non-right angle α, that is the ratio of the adjacent side of a right triangle to its hypotenuse.
Adjacent Side of Angle Alpha - (Measured in Meter) - Adjacent Side of Angle Alpha is the length of the non-hypotenuse edge of a right triangle which is adjacent to the given non-right angle α.
Hypotenuse Side - (Measured in Meter) - The Hypotenuse Side of Right Angled Triangle is the longest side of the right-angled triangle and it is the side opposite to the right angle (90 degrees).

STEP 1: Convert Input(s) to Base Unit

Adjacent Side of Angle Alpha: 3 Meter --> 3 Meter No Conversion Required
Hypotenuse Side: 5 Meter --> 5 Meter No Conversion Required

What is Trigonometry?

Trigonometry is the branch of mathematics that deals with the relationships between the angles and sides of triangles, particularly right triangles. It is used to study and describe properties such as lengths, angles, and areas of triangles, as well as the relationships between these properties and the properties of circles and other geometric shapes. Trigonometry is used in many fields, including physics, engineering, and navigation.
