If the ship is traveling 24 miles per hour, then after 2 hours it will have traveled 48 miles:
The difference between the two courses (Planned Course and Actual Course) form a triangle where the Actual Couse is the hypotenuse of the triangle and is a length of 48 miles like this:
The trig ratio "sine" is the ratio opposite over hypotenuse so:
sin(2.6°) = x/48
Can you solve this equation using your Algebra skills?
