Which expression can be used to find the value of x?

       23 sin 55°

x =           (matches first answer choice)

          sin 85°

Step-by-step explanation:

Note that 2 angles and 1 side length are given.  This is a typical application of the Law of Sines.  The formula for finding the length of side x is:

       23 sin 55°

x =           (matches first answer choice)

          sin 85°

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.
