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.
30 feet is correct. Since a = 3b, the wingspan is 6 inches in the drawing, so it is 6x5 = 30 feet on the plane.
