The boy is in the ocean at an angle of 35 degrees from us. We are 28 feet above the ground.
We need to figure out how far the boy is, so we need to use 28/tan(35). We are approx, 40ft from the boy. Before rescuing the boy, it wouldn't be bad to find out how fast the helicopters blades are moving, so we can ensure a safe landing. One blade is 12ft, and rotates around 500rpm.
We need to check the height of the waves to see how low we can fly.
To find out how fast the blades are moving, we need to use the formula 2π(12)(500), and we can figure out that the blades travel 37699ft/min
