Solve Find the angle between vectors a = (10, -2) and b = (-10, -2). — Step-by-Step Solution by AhaStep

📝 Problem

Find the angle between vectors a = (10, -2) and b = (-10, -2).

1. 📝 Summary: v = (-10$ , -2)

2. 🧮 Dot Product: u · v = -96

3. 📐 Magnitudes: |u| = 10.19803903, |v| = 10.19803903

4. 🎯 Angle: cos(θ) = (u·v)/(|u|·|v|) = -96/(10.19803903·10.19803903) = -12/13
