Solve Angles from Values (Level 1)

This math topic focuses on solving for unknown angles using trigonometric principles, specifically involving calculations using various side lengths of triangles (opposite, adjacent, hypotenuse). The problems provide measurements of two sides and require determining the angle, helping reinforce the application of trigonometric ratios such as sine, cosine, and tangent. This set of problems is designed as an introductory level of trigonometry, suitable for beginning learners who are just familiarizing themselves with the basics of trigonometric relationships in right-angled triangles.
