Adjacent Side Formula:
| From: | To: |
The adjacent side of angle alpha in a right triangle is the side that forms the angle alpha along with the hypotenuse. It is the non-hypotenuse edge that is next to the given angle alpha.
The calculator uses the trigonometric formula:
Where:
Explanation: The formula uses the tangent ratio which relates the opposite side to the adjacent side in a right triangle.
Details: Calculating the adjacent side is fundamental in trigonometry and has applications in various fields including engineering, physics, architecture, and navigation where right triangle relationships are used.
Tips: Enter the opposite side length in meters and the angle alpha in degrees. The angle must be between 0° and 90° (non-inclusive) for valid results.
Q1: What is the range of valid angles for this calculation?
A: The angle alpha must be between 0° and 90° (exclusive) for the tangent function to be defined and meaningful in a right triangle context.
Q2: Can this formula be used for any triangle?
A: No, this specific formula applies only to right triangles where one angle is exactly 90 degrees.
Q3: What if the angle is 90 degrees?
A: At 90 degrees, the tangent function is undefined, so the calculation is not possible with this formula.
Q4: How accurate is this calculation?
A: The accuracy depends on the precision of your inputs. The calculator uses PHP's built-in trigonometric functions which provide high precision.
Q5: Can I use different units of measurement?
A: The formula works with any consistent units, but the calculator is set up for meters. You can use other units as long as you're consistent with your measurements.
