Keep trying at this question, I believe in you! Here's the answer just in case. :)
Answer: 0.83644865915
Nearest hundredth would be 0.84.
I can explain it if you'd like.
Edit: Here's how I did it just in case anybody wants to know :) Not that anybody wants to know but just in case because you never know! :)
SOH CAH TOA
sine=opposite/hypotenuse
cosine=adjacent/hypotenuse
tangent=opposite/adjacent
So the cosine of W would be 65(the adjacent side)/97(the hypotenuse)
Because you don't know what W equals, you'd use a calculator and click the little 2nd button, then click the cos button. And then you'd type in the 65/97 and hit the equals button and that's the answer!
If I'm incorrect I guess tell me somehow? Alright, have a great day/night! ^-^
Answer:

Step-by-step explanation:

Answer: B) (x-1)2+(y+1)2= 25 radius = 5 miles
Step-by-step explanation:
In order to get this answer you see that you are adding a negative to x in the first part then multiplying it by 2. Second, you add y+1 then multiplying it by 2. You get the radius of 25 which equals 5 miles. Look at the graph to also check your answers to the problem.
