Question:

16. The three shown circles, with radius 15 in., 10.5 in., and 4.5 in., are tangent to each other.

(a) Calculate the angle y (in degrees) by using the law of cosines (Law of cosines: +b-2abcos)

(b) Calculate the angles y and a (in degrees) using the law of sines.

(c) Check that the sum of the angles is 180.
