Solve for x, x= blank degrees. may you also tell me how so i can understand it?
4 sided polygon, not a square
the given degrees are 121, 108, 102, and 100

In triangle abc, the length of side ab is 12 cm, the length of side bc is 5 cm, and the length of side ca is 9 cm. find the measure of angle a using the law of cosines.

If you are just building your payment history, how many points from a perfect score will you possibly miss?

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.
