Cot²x /(cscx + 1) = (1 - sinx) /sinx
let's apply the identity cot²x = csc²x - 1:
(csc²x - 1) /(cscx + 1) = (1 - sinx) /sinx
(factoring csc²x - 1 as a difference of squares and then simplifying)
[(cscx + 1)(cscx - 1)] /(cscx + 1) = (1 - sinx) /sinx
cscx - 1 = (1 - sinx) /sinx
let's recall that cscx = 1 /sinx:
(1 /sinx) - 1 = (1 - sinx) /sinx
ending with:
(1 - sinx) /sinx = (1 - sinx) /sinx (verified)
I hope it helps
You use Pythagoras' Theorem and the theorem of 30-60-90 triangle
Answer:
19. The United States declared war on Britain in 1812. It did so because Britain refused to stop seizing American ships that traded with France—Britain's enemy in Europe. Sometimes there were also seizures of American sailors. These seizures were known as impressment

sorry man im just answering for points
Step-by-step explanation:
Hey! So this is pretty straightforward. You're given all the information already and now you just have to do some calculations.
60 + 30w = 480
You can start by subtracting 60 from both sides
30w = 420
Now you need to get w by itself so you have to divide both sides by 30 and you will end up getting
w = 14!
