Definition: This calculator computes the length of a side in a right-angled triangle given the hypotenuse and an angle.
Purpose: It helps students, engineers, and designers quickly determine side lengths in right-angled triangles for various applications.
The calculator uses the trigonometric formula:
Where:
Explanation: The sine function relates the angle to the ratio between the opposite side and hypotenuse in a right-angled triangle.
Details: These calculations are fundamental in geometry, physics, engineering, architecture, and many practical applications like construction and navigation.
Tips: Enter the hypotenuse length in meters and the angle in degrees (must be between 0 and 90). All values must be positive numbers.
Q1: What if I know the adjacent side instead of the hypotenuse?
A: Use the cosine function instead: \( a = adj \times \tan(\theta) \).
Q2: Why does the angle need to be less than 90 degrees?
A: In a right-angled triangle, the other two angles must be acute (less than 90°) since all angles sum to 180°.
Q3: How accurate are the results?
A: Results are mathematically precise based on the inputs, though practical measurements may have slight variations.
Q4: Can I use this for non-right-angled triangles?
A: No, this calculator is specifically for right-angled triangles. For other triangles, use the Law of Sines or Cosines.
Q5: What units should I use?
A: The calculator uses meters, but you can use any unit as long as you're consistent (all lengths in the same unit).
