The ratio of cos S in triangle RQS is 48 / 73

Right angle triangle:

  • It has one angle as 90 degree
  • The sides can be found using Pythagoras theorem

∠Q = 90 degrees

Therefore, Finding cos S,

opposite side = RQ = 55

Hypotenuse = RS = 73

Adjacent side = QS = 48

Therefore,

cos S = adjacent / hypotenuse

cos S = 48 / 73
