Law of Cosines can be used to solve SSA problems, you just
need to solve a quadratic equation.
(a) Use the Law of Cosines to write a quadratic equation in
terms of x, the length of the base of this triangle. Rewrite your
equation so that one side is 0 and write it below. Round decimals
to 2 places and in the standard form of ax² + bx+c.
0-
(b) What are the two solutions to this quadratic equation? Write
them in order from least to greatest. These are the two different
lengths that x could be.
