Answer 1

Answer:

The answer to your question is:

a) cot B = 1/2

b) cos A = 2√5 / 5

c) csc B = √5 / 2

Step-by-step explanation:

Data

BC = 4

AC = 8

Pythagorean theorem

                                    AB² = AC² + BC²

                                    AB² = 64 + 16

                                    AB² = 80

                                    AB = $\sqrt{80}  =  4\sqrt{5}$

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

cos A = adjacent side / hypotenuse = 8/4√5 = 2$\sqrt{5} / 5$

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

Answer 2

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.
