Trigonometry help please? :)?
Bruce and Ernie are 636 m apart on the ground while Elmo flies overhead in a plane between them. Bruce measures the angle of elevation to be 63 degrees, Ernie measure the angle of elevation to be 36 degrees. The altitude of Elmos plane is 636m / [cot 63 + cot 36] = 343 m
