1. What is a Right Angle Triangle Trigonometry Calculator?

Definition: This calculator determines the angle in a right triangle when given the lengths of the opposite and adjacent sides.

Purpose: It helps students, engineers, and professionals quickly solve right triangle problems using trigonometric principles.

2. How Does the Calculator Work?

The calculator uses the tangent formula:

Where:

• \( \theta \) — Angle in degrees
• opposite — Side opposite to angle θ
• adjacent — Side adjacent to angle θ

Explanation: The calculator takes the arctangent (inverse tangent) of the ratio of opposite to adjacent sides to find the angle.

3. Importance of Trigonometry Calculations

Details: Right triangle trigonometry is fundamental in construction, navigation, physics, and engineering applications.

4. Using the Calculator

Tips: Enter the lengths of the opposite and adjacent sides in meters (or any consistent unit). Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What if I know the hypotenuse instead?
A: Use sine (opposite/hypotenuse) or cosine (adjacent/hypotenuse) instead of tangent.

Q2: Can I use different units for the sides?
A: Yes, as long as both sides use the same unit (meters, feet, etc.).

Q3: What's the range of possible angles?
A: For right triangles, θ will always be between 0° and 90°.

Q4: How accurate are the results?
A: Results are accurate to two decimal places, sufficient for most practical applications.

Q5: Can this calculate side lengths if I know the angle?
A: No, this version calculates angles from sides. A different calculator would be needed for that function.
