Do you want to improve your mind, become genuinely intelligent, and thrive in a world where the only constant is change?
An intelligent mind — a force in the storm — is the key to navigating life’s challenges.

Today, we’re diving into a geometric problem that uses the Cosine Rule to unlock the unknown side of a triangle. The Cosine Rule isn’t just a formula — it’s a tool that transforms how you approach non-right-angled triangles, giving you the edge in solving geometric puzzles.

📐 Problem Breakdown:

We’re given:

Triangle ABC, with sides AB = 4, BC = √7, and an included angle of 60°.

The task: Find the missing side AC.

🎯 Objective:
Use the Cosine Rule to find the length of side AC and sharpen your problem-solving skills.

🔑 Cosine Rule Formula:

The Cosine Rule is essential for solving triangles when you know:

Two sides and the included angle

Or all three sides of the triangle

🧠 Why is this Important?

Mastering the Cosine Rule helps you tackle non-right-angled triangles, an essential skill in:

Geometry problem-solving

Competitive exams

Real-world applications like physics, architecture, and engineering

🎯 Your Challenge:

How quickly can you apply the Cosine Rule?

Try solving it before the solution is revealed. Apply your spatial intelligence and mathematical reasoning to find AC in the triangle!
