3. Test From a point 50 meters from the base of a building, the angle of elevation to the top is 40°. How far is it from that point directly to the top of the building? A kite is flying with 80 meters of string let out. The string makes a 55° angle with the ground (assuming the string is straight). How high is the kite? A ramp is 15 meters long and rises 3 meters vertically. What angle does the ramp make with the ground?
