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
