<PRE><B>Question 455002</B>
How can we find the length of one side of a triangle when two sides and an angle is given using Sine and cosine? please give an example.
-----------------
Use Law of Cosines:
Example
If a = 3 and b = 4 and angle C = 30 degrees,
---
c^2 = a^2 + b^2-2ab*cos(C)
---
c^2 = 3^2+4^2-2*12*(sqrt(3)/2)
---
c^2 = 25-12*sqrt(3)
--
c = sqrt[4.215..]
c = 2.053
