Answer:
x = 18
Step-by-step explanation:
Since that is a right angle, we know that the total degrees of the angle is 90 degrees.
1) Based off of that, you can form the equation: 3x + 2x = 90.
2) solve the equation for x. Combine like terms: 3x + 2x = 5x.
5x = 90
3) So now, divide both sides by 5. 90 / 5 = 18
x = 18
Therefore, the correct answer is x = 18.
Notice that the condition <em>x</em> ≠ 2<em>πk</em> for (presumably) integer <em>k</em> means cos(<em>x</em>) ≠ ±1, and in particular cos(<em>x</em>) ≠ 1 so that we could divide both sides by (1 - cos(<em>x</em>)) safely. Doing so lets us separate the variables:
(1 - cos(<em>x</em>)) <em>y'</em> - <em>y</em> sin(<em>x</em>) = 0
==> (1 - cos(<em>x</em>)) <em>y'</em> = <em>y</em> sin(<em>x</em>)
==> <em>y'</em>/<em>y</em> = sin(<em>x</em>)/(1 - cos(<em>x</em>))
==> d<em>y</em>/<em>y</em> = sin(<em>x</em>)/(1 - cos(<em>x</em>)) d<em>x</em>
Integrate both sides and solve for <em>y</em>. On the right, substitute <em>u</em> = 1 - cos(<em>x</em>) and d<em>u</em> = sin(<em>x</em>) d<em>x</em>.
∫ d<em>y</em>/<em>y</em> = ∫ sin(<em>x</em>)/(1 - cos(<em>x</em>)) d<em>x</em>
∫ d<em>y</em>/<em>y</em> = ∫ d<em>u</em>/<em>u</em>
ln|<em>y</em>| = ln|<em>u</em>| + <em>C</em>
exp(ln|<em>y</em>|) = exp(ln|<em>u</em>| + <em>C </em>)
exp(ln|<em>y</em>|) = exp(ln|<em>u</em>|) exp(<em>C </em>)
<em>y</em> = <em>Cu</em>
<em>y</em> = <em>C</em> (1 - cos(<em>x</em>))
Answer:
i can't see the question right but you basically just multiply the number by itself (as many times as the exponent says)for the answer
also when you find the top number divide it by the bottom number to get your answer

if the picture was clearer I could help you more
The correct answer is this:
cos π = -1.
