Solve the given triangle. round the measures of sides to the nearest tenth and measures of angles to the nearest degree.
c = 8, b = 50°, c = 55°

question 5 options:

a = 75°, a = 63.6, b = 7.5

a = 75°, a = 7.5, b = 9.4

a = 75°, a = 9.4, b = 7.5

a = 75°, a = 8, b = 7.5

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
