Homework Statement
Hello all, I am having trouble with the following homework question using trigonometric formulas and the Sine Law.
Here is the problem:
Jack spotted a hot air balloon from his house at angle of elevation 57 degrees. Jack's friend who lives 26 km from Jack's house spotted the same balloon at angle of elevation 83 degrees. Determine the altitude of the balloon to the nearest tenth.
Homework Equations
Sine Laws: [(sinA/a)=(sinB/b)=(sinC/c)], Trigonometric Functions: (SOH, CAH, TOA)
The Attempt at a Solution
Here is my solution:http://img143.imageshack.us/img143/4566/hotairballoonqc2.jpg However, the answer given in the text was 49.4 km.
Whereas, my answer is 33.7 km.
Can anybody tell me where I went wrong.
Thanks a lot.
