Input the following measurements into a triangle calculation tool. What is the length of side c given the following measurements?
Angle C = 25°, side b = 3 units, side a = 20 units
Using the given measurements and the Law of Sines, the length of side c can be calculated as:
c = sqrt(a^2 + b^2 - 2ab * cos(C))
c = sqrt(20^2 + 3^2 - 2*20*3 * cos(25))
c = sqrt(400 + 9 - 120 * cos(25))
c = sqrt(409 - 120 * cos(25))
c ≈ 19.16 units
Therefore, the length of side c is approximately 19.16 units.
