Solve Find the angle between vectors a = (-7, -4) and b = (-4, -8). — Step-by-Step Solution by AhaStep

📝 Problem

Find the angle between vectors a = (-7, -4) and b = (-4, -8).

1. 📝 Summary: v = (-4$ , -8)

2. 🧮 Dot Product: u · v = 60

3. 📐 Magnitudes: |u| = 8.062257748, |v| = 8.94427191

4. 🎯 Angle: cos(θ) = (u·v)/(|u|·|v|) = 60/(8.062257748·8.94427191) = 0.8320502943
