If the length of fh is 18 units, what is the value of x?

solution

              to   find   the   value   of   "x"   .

              given   the   length   of     fh   is   "18"   units  

              from   the   figure     we   have  

                  fh   =   fg   +   gh  

                  fh   =   4x   + 2x

                  fh   =   6x  

              given   fh   = 18   units

                            6x   =   18  

                            x   =   18 / 6

                            x =   3

                      therefore   , value   of   x =   3   units

                      hence   , option   a  

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
