Solve for x. Round your answer to 2 decimal places. 14.38 10.83 22.54 29.91

cos 90? cos 90 is actually = 0. i think you're trying to find cos 53 which is actually 18/x :)

@hartnn so you would set it up as cos 53 = 18 / x
hartnn
  • hartnn
yes, correct

find x

to get x by itself you would do multiply both sides by 1/18 to get x by itself? because by doing that i get a small decimal
hartnn
  • hartnn
yes you'd get x = 18/ cos 53 and use cos 53 = 0.602
