Aidan and Blake are 626 m apart. Cody flies overhead in a plane between them. At the same time, they measure the angle of elevation of the plane. Aidan measures the angle of elevation to be 63 degrees. Blake measures it to be 36 degrees. What is the altitude (height) of the plane? Include a diagram.
