Question 1199075: A rocket tracking station has two telescopes A and B placed 2.6 miles apart. The telescopes lock onto a rocket and transmit their angles of elevation to a computer after a rocket launch. What is the distance to the rocket from telescope B at the moment when both tracking stations are directly east of the rocket telescope A reports an angle of elevation of 29° and telescope B reports an angle of elevation of 43°?

You can put this solution on YOUR website! .
This problem is to apply the sine law twice.
First find the angle, opposite to the side of the triangle, which is 2.6 miles long.
-----------------
On the Sine law, see the lessons
- Law of sines - the Geometric Proof
- Solve triangles using Law of Sines
In addition to the theory, clearly explained, you will find there many solved problems, that are your TEMPLATES.
Consider these lessons as your handbook, textbook, guidelines, tutorials and (free of charge) home teacher.
Happy learning ( ! )
