Answer:
A
Step-by-step explanation:
We can write this as Sinx by "flipping" the 
.
So we will have: 
From basic trigonometry, we know the value of 
of sine is of the angle 
<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and 
, <em>so we disregard 4th quadrant.</em>
<em />
<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>
A is the right answer.
I just answered this question few minutes ago
yes, you are right
Answer: air pressure
Whenever you hear things like "high pressure" or "low pressure" on weather reports, they measured the pressure using a barometer. Knowing the air pressure helps determine if there is a higher chance of rain or storms for instance.
Typically but not always, high pressure correlates to sunny days and dry weather. Low pressure often brings about rain. This is of course a very oversimplified viewpoint.
