1. What is Angle Calculation?

Angle calculation using the arctangent function determines the angle of a right triangle when you know the lengths of the opposite and adjacent sides. This is fundamental in trigonometry and has applications in navigation, engineering, and physics.

2. How Does the Calculator Work?

The calculator uses the arctangent formula:

Where:

• \( \text{opposite} \) — Length of the side opposite the angle
• \( \text{adjacent} \) — Length of the side adjacent to the angle
• The result is converted from radians to degrees

Explanation: The arctangent function (inverse tangent) returns the angle whose tangent is the ratio of opposite to adjacent sides.

3. Importance of Angle Calculation

Details: Calculating angles is essential in fields like construction (roof pitches), aviation (flight paths), and computer graphics (object rotations). Accurate angle measurement ensures proper alignment and orientation in these applications.

4. Using the Calculator

Tips: Enter the lengths of the opposite and adjacent sides in any consistent units (both must be positive numbers). The calculator will return the angle in degrees.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between radians and degrees?
A: Degrees divide a circle into 360 parts, while radians use 2π (about 6.28). This calculator converts the result to more familiar degrees.

Q2: Can I use this for non-right triangles?
A: No, this specific formula only works for right triangles. For other triangles, you'd need the Law of Cosines or Law of Sines.

Q3: What if my adjacent side is zero?
A: The adjacent side cannot be zero as it would make the ratio undefined (division by zero). This represents a vertical line with a 90° angle.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, though practical accuracy depends on your input measurements and the precision of your calculator.

Q5: Can I calculate the hypotenuse with this?
A: Not directly, but you could use the Pythagorean theorem (√(opposite² + adjacent²)) once you have both sides.
