(a - b) . (6a + b) = 0
6|a|² - 5ab - |b|² = 0
6(2)² - 5ab - 3² = 0
6(4) - 9 = 5ab
5ab = 15
ab = 3

So...
Cos β = (ab)/(|a| |b|)
Cos β = 3/(2 . 3)
Cos β = 3/6
Cos β = 1/2
Cos β = Cos 60°
β = 60°

5.On last Wednesday, I've got unforgettable experience. The day before, I played game on-lineuntil 00.00 am. Because of that I woke up late. It was about 7.30 am and the class would be started at 8.00 am. I ran to bathroom to take a bath. I used to have breakfast before leaving home, but on that day It was impossible. I always rode motorcycle to go. But what an amazing thing happened, I forgot where I put thekey. So, I went to campus by public transportation. Of course, it took longer time. I arrived at 8.15 am, I hurried to get to class but I saw my lecturer standing in front of the class to teach. I entered my classroom and you know what, he was angry to me and didn't let me join his material. It was my bad experience and I hoped I would not do that again.

What should the writer do to avoid being late again to his campus?

Jawabannya:C
