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)

Answer:
$21
Step-by-step explanation:
Take 40 percent of 35:
35(0.4) = 14
$14 has been taken off the original price:
35 - 14 = 21
And we have our final answer.
The two triangles are similar all angles are equal.
the sides are proportional
10/22 = AQ/AQ + 18
22AQ = 10 AQ+ 180
12 AQ = 180
AQ = 15
Answer:
A: 12
Step-by-step explanation:
Using the pythagoreom theorem, a^2+b^2=c^2. We can plug in the lengths of 5 and 13 which is 5^2+b^2=13^2. Now we can square the numbers to get 25+b^2=169. Subtract 25 from 169 to get 144. Now find the square root of 144 which is 12.
