A scuba diver drops into the water from a dive boat and descends to a coral reef at a depth of 20 m. She follows the reef in a westerly direction. She estimates that she has traveled 30 m along the reef. The diver continues to follow the reef, which turns 30 degrees to the right, swimming for another 25 m without changing depth. At this point, how far is she from the dive boat? (I just need a diagram, tysm!)
