The angles of elevation to an airplane from two points A and B on level ground are 56° and 73°, respectively. The points A and B
are 2.2 miles apart, and the airplane is east of both points in the same vertical plane. Find the altitude of the plane. (Round your answer to two decimal places.)
1 answer:
Answer:
The altitude of the plane = 5.97 miles to 2 d.p
Explanation:
Let the altitude of the plane be H miles
Let the distance between point B and the foot of the straight vertical altitude of the plane be x miles
The distance between point A and the straight vertical altitude of the plane is (x + 2.2) miles
