You are given a triangle with two sides A 95 cm and B 326 cm, and the angle between these sides is 30 degrees. What is the length of the unknown side C of the triangle?
297.98 cm
248.31 cm
190 cm
128 cm
Select your answer and then check it
\( c^2 = a^2 + b^2 - 2ab \cos(\theta) \)
\( c = \sqrt{95^2 + 326^2 - 2\times95\times326 \cos(30)}\)
