Sine Rule
a/Sine A = b/Sine B = c/Sine C

a is the length opposite Angle A
b is the length opposite Angle B
c is the length opposite Angle C

As the sum of the angles is 180
180 - 120 = 60
60/2 = 30 (The Other Angles)

3/Sine 30 = 6
Thefore, length = 6 * Sine 120
=5.196

Try this one:

"The Dean's penis is larger than The Shed's by a factor of 2.4. Prove that The Dean is more popular with the ladies by a factor of 7.2."
