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 \(\sin \angle ACB\)?
(There were no images given for any of these questions.)
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
