He said that the radian measure of angles A and B in Circle 1 and Circle 2, respectively is not the same.
Circle 1 has radius 5, while Circle 2 has radius 6.25. Angle A in Circle 1 intercepts an arc of length 10/9 π, and, angle B in Circle 2 intercepts an arc of length 25/18 π.
Who is incorrect? Both angles measure 2/9 π
As shown above, a canoe is approaching a lighthouse on the coastline of a lake. The front of the canoe is 2 feet above the water and an observer in the lighthouse is 120 feet above the water.
At 8:00, the observer in the lighthouse measured the angle of depression to the front of the canoe to be 10°. Five minutes later, the observer measured and saw the angle of depression to the front of the canoe had increased to 40°. What is the distance, rounded to the nearest tenth, that the canoe traveled toward the lighthouse, from 8:00 am to 8:05 am?.
