1. What is the Area of Triangle given Sides A and C and Sine of Angle B?

This formula calculates the area of a triangle when two sides and the included angle are known. It's particularly useful when you have sides A and C and the angle between them (Angle B).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Side A \) — Length of side A of the triangle (meters)
• \( Side C \) — Length of side C of the triangle (meters)
• \( Angle B \) — Angle between sides A and C (degrees)
• \( \sin \) — Trigonometric sine function

Explanation: The formula calculates the area by taking half the product of two sides multiplied by the sine of the included angle.

3. Importance of Triangle Area Calculation

Details: Calculating triangle area is fundamental in geometry, engineering, architecture, and various scientific applications. This specific formula is valuable when the included angle is known rather than the height.

4. Using the Calculator

Tips: Enter side lengths in meters and angle in degrees. All values must be positive numbers. Angle B must be between 0 and 180 degrees.

5. Frequently Asked Questions (FAQ)

Q1: Why use this formula instead of base × height/2?
A: This formula is useful when the height is unknown or difficult to measure, but two sides and the included angle are available.

Q2: What if the angle is not between sides A and C?
A: This formula only works when the given angle is the included angle between the two specified sides.

Q3: Can this formula be used for any type of triangle?
A: Yes, this formula works for all types of triangles - acute, obtuse, and right triangles.

Q4: What are the units of measurement?
A: Side lengths should be in consistent units (meters), and the area will be in square units (m²).

Q5: How accurate is the calculation?
A: The accuracy depends on the precision of your input values. The calculator provides results with up to 6 decimal places.
