Please helpp, math unit test tomorrow!!!!

Question

A commercial plane and a jet airliner are 7.5km from each other, at the same altitude. From an observation tower, the two aircraft are separated by an angle of 68⁰. If the jetliner is 5.2km from the observation tower, how far is the commercial plane from the observation tower?

 

 

Answer 1

sorry there is no tool to drawn the picture to explain the answer for this problem. Here is the answer

 

The distance from commercial plane to the observation tower is :

d = 5.2*cos68 + sqrt (7.2²  - (5.2*sin68)²)
