Page 1: Basic Trigonometric Calculations

This page introduces fundamental trigonometric calculations focusing on Calculate triangle side length nearest tenth MBF3C. The content covers four main problem types involving finding side lengths and angles in triangles.

Example: Problem 2 demonstrates finding both an angle and side length, resulting in x = 14.4cm.

Highlight: The page emphasizes the importance of rounding answers to the nearest tenth for measurements and nearest degree for angles.

Vocabulary: Key trigonometric ratios (sine, cosine, tangent) are utilized throughout the problems.

Definition: The Pythagorean theorem (a² + b² = c²) is applied for right triangle calculations.
