In this video we will explore how to use inverse trigonometry to find the missing angles of a right triangle.

Here is the revised description with all the links and additional text removed: Learn how to solve trigonometric equations.

There are two versions of the cosine rule: Find an unknown side using 𝑎² = 𝑏² + 𝑐² – 2𝑏𝑐 cos𝐴 Find an unknown angle using cos𝐴 = \(\frac{𝑏² + 𝑐² – 𝑎²}{2𝑏𝑐}\) Scientific calculators need to ...
