In this video, we walk through a step-by-step solution for the Leaving Certificate Ordinary Level (LCOL) 2024 Paper 2, Question 8 (b). We focus on trigonometry, specifically how to identify when to use the Sine Rule versus the Cosine Rule to find a missing angle. We cover: Deciding if a triangle is right-angled or not. Using the Log Tables (Formulae and Statistical Tables) effectively. Setting up the Sine Rule equation. Solving for a missing angle using the inverse sine function. Rounding your final answer to the nearest degree. Whether you are preparing for your mocks or the final exam, this breakdown will help you master trigonometric problems in the Leaving Cert curriculum. 0:00 Introduction to the logo problem 0:21 Identifying given measurements 0:54 Navigating the Formulae and Statistical Tables 1:04 Choosing between Sine Rule and Cosine Rule 2:44 Labeling the triangle 4:00 Plugging values into the Sine Rule formula 4:24 Solving the equation with cross multiplication 5:15 Calculating the inverse sine 5:37 Final answer and rounding Leaving Cert Maths, LCOL 2024, Paper 2 Question 8, Sine Rule, Trigonometry, Irish Maths, Leaving Cert Ordinary Level, Finding a missing angle, Maths School of Grinds, Leaving Cert Solutions, Project Maths Ireland
