Solve Find the angle between vectors a = (6, 5) and b = (-8, 1). — Step-by-Step Solution by AhaStep

📝 Problem

Find the angle between vectors a = (6, 5) and b = (-8, 1).

1. 📝 Summary: v = (-8$ , 1)

2. 🧮 Dot Product: u · v = -43

3. 📐 Magnitudes: |u| = 7.810249676, |v| = 8.062257748

4. 🎯 Angle: cos(θ) = (u·v)/(|u|·|v|) = -43/(7.810249676·8.062257748) = -0.6828838781
