Laura is flying to Italy over her spring break to visit her friend, Brittany, who is studying abroad in Siena, Italy. Laura will land at the airport in Rome after an 8 hour flight, grab her bags and hop a train for the hour’s trip to Siena. If her flight leaves Toronto at 9 AM Thursday and it will take an hour to get her bags and go through customs in Rome, what time (and day) should Laura tell Brittany to expect her on her doorstep?

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
