WebDetermine the angle between vectors a and b ( a ≠ 0, b ≠ 0) if a + 3 b is perpendicular to 2 a − b and a + 7 b is perpendicular to 2 a + b. I've done this: ( a + 3 b) ⋅ ( 2 a − b) = 0 … 5 a ⋅ b = 3 b ⋅ b − 2 a ⋅ a ( a + 7 b) ⋅ ( 2 a + b) = 0 ⋯ 15 a ⋅ b = − 2 a ⋅ a − 7 b ⋅ b which gives me: a ⋅ b = ( − ( b ⋅ b + a ⋅ a)) / 5
