A sailboat is sailing due east at 5.40 mph. The wind appears to blow from the southwest at 13.4 mph.(adsbygoogle = window.adsbygoogle || []).push({});

1. What is the true wind speed?

2.What is the true wind direction? ( south of west).

3.What is the true wind speed if the wind appears to blow from the northeast at 13.4 mph?

4.What is the true wind direction ( north of east) if the wind appears to blow from the northeast at 13.4 mph?

I tried solving the first question but did not get the correct answer. I know if you get the first question right it is easy to solve the second. Here's what I tried

sqrt ((13.4*sqrt (2)- 5.4)^2 + (13.4* sqrt(2))^2))= 23.29 mph but it wasn't right

this is Ax part this is Ay part

after finding the Ax and Ay just plug into equation:

theta=arctan(Ax/Ay)

PLEASE HELP ASAP NEED BY TONIGHT!!!!!
