Angle Calculation Formula:
From: | To: |
The Degree Of Angle Calculator calculates the angle in degrees from the opposite and adjacent sides of a right triangle using trigonometric functions. This is essential for geometry, engineering, and various mathematical applications.
The calculator uses the trigonometric formula:
Where:
Explanation: The arctangent function calculates the angle in radians, which is then converted to degrees using the conversion factor.
Details: Accurate angle calculation is crucial for geometry problems, engineering designs, construction projects, navigation, and various scientific applications where precise angular measurements are required.
Tips: Enter the length of the opposite side and adjacent side in any consistent units (meters, feet, etc.). Both values must be positive numbers greater than zero.
Q1: What is the range of angles this calculator can compute?
A: This calculator computes angles from 0° to 90° for right triangles. For other triangles, additional calculations are needed.
Q2: Can I use this for non-right triangles?
A: No, this calculator specifically uses the tangent function which applies only to right triangles. For other triangles, use the Law of Sines or Cosines.
Q3: What if both sides are equal?
A: If opposite and adjacent sides are equal, the angle will be exactly 45°, as tan(45°) = 1.
Q4: How accurate is the calculation?
A: The calculation is mathematically precise, with results rounded to 2 decimal places for readability.
Q5: What units should I use for the side lengths?
A: You can use any consistent units (meters, centimeters, feet, etc.) as long as both sides are measured in the same units.
