Trigonometry is often aligned with right-angled triangles only. However, an understanding of trigonometry can also be extended to non-right angle triangles to find unknown sides or angles. The Sine ...

Use this formula when given the sizes of two sides and its included angle.

This version is used to calculate lengths. Calculate the length BC. Give the answer to three significant figures. Use the form \(a^2 = b^2 + c^2 - 2bc \cos{A}\) to calculate the length. \(\text{BC}^2 ...
