A surveyor found the angle of elevation from the ground to the top of the building at two locations 20 feet apart as shown below. 2 lines are drawn from the ground to the top of a building, forming 2 triangles with the ground. The angle of elevation of the first line is 48 degrees. The second line is 20 feet away from line 1. The angle of elevation of the second line is 33 degrees. c is the length of the first line and h is the height of the building. Angle A is the angle to the left of angle 48 degrees, and angle B is the angle at the convergence of the 2 lines with the top of the building. Which measurements are correct? Round side lengths to the nearest hundredth. Check all that apply. m∠A = 57° m∠B = 15° c ≈ 10.89 ft h ≈ 8.09 ft h ≈ 31.28 ft

an altitude of 15,000 feet
