B (6, 1), (10, 8), (14,22), (22, 50)

C (6, 1), (8, 8), (12, 20), (20, 45)

D (6, 1), (8, 8), (12, 22), (20, 50)

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations
