Does anyone know the answer to this word problem?
Grace is standing 14 feet from a lighthouse and Kelly is standing 12 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°.
a.find the height, h, of the lighthouse.
b.Find the angle, rounded to the nearest tenth of a degree, in which Kelly looks up to the top of the lighthouse.
c.To the nearest tenth of a degree, find the value of x° . In two or more sentences, explain your calculations
