Answer 1

Well, I was going to say exactly what the person said before me. So, I guess that doesn't really help. You can just delete this if you want. Sorry to bother you.

Answer 2

The answer to your question is:

a) cot B = 1/2

b) cos A = 2√5 / 5

c) csc B = √5 / 2

Explanation:

Data

BC = 4

AC = 8

Pythagorean theorem

AB² = AC² + BC²

AB² = 64 + 16

AB² = 80

AB =
`√(80)  =  4√(5)`

Cot B = adjacent side / opposite side = 4/8 = 1/2

cos A = adjacent side / hypotenuse = 8/4√5 = 2
`√(5) / 5`

csc B = hypotenuse / opposite side = 4√5 / 8 = √5/2
