1. Degrees are not the only units we use to measure angles. We also use radians. Just as there are \(360^\circ\) in a circle, there are \(2\pi\) radians in a circle. Compute \(\sin \frac{\pi}{6},\) where the angle \(\frac{\pi}{6}\) is in radians.

 

2. In triangle \(ABC\)\(AB = BC = 25\) and \(AC = 40\). What is \(\sin \angle ACB\)?

Thank you so much for your help!

pi/6   is   30o

 

pi/6 R x 180o/(pi R) = 30 degrees    sin 30 degrees  = sin pi/6 = 1/2
