2. A lifeguard standing at the water's edge sees a man flailing out in the water. She runs along the shore 40 m, then turns 45° and swims another 20 m to reach him. a. How far was the lifeguard from the flailing man originally? (Be sure to draw a picture of the situation, and of the path that the lifeguard takes. To help make sure that you start with the correct triangle, think about what it means to turn 0° or 1° and also what it means to turn 180° or 179°. And then think about what this means about the 60° angle in the question-is it an internal or external angle to the triangle that you need to draw?) distance to the flailing man = b. How far offshore was the man flailing (assuming a straight beach)?

a.
How far was the lifeguard from the flailing man originally? (Be sure to draw a picture of the
situation, and of the path that the lifeguard takes. To help make sure that you start with the correct
triangle, think about what it means to turn 0° or 1° and also what it means to turn 180° or 179°. And
then think about what this means about the 60° angle in the question is it an internal or external
angle to the triangle that you need to draw?)
distance to the flailing man,
b. How far offshore was the man flailing (assuming a straight beach)?
distance offshore =
