\[ \sin(x)=\frac{\text{opposite}}{\text{hypotenuse}}\\ \cos(x)=\frac{\text{adjacent}}{\text{hypotenuse}}\\ \tan(x)=\frac{\text{opposite}}{\text{adjacent}}=\frac{\sin(x)}{\cos(x)} \]

Sin 33 = x over 7 x = 7 times sin 33 x =3.81

so for this one you finding the hypotenuse( base of the triangle), right?
sebastiangonzagonza
  • sebastiangonzagonza
i believe so
anonymous
  • anonymous
now look at the figure, is the same thing again : opposite over hypotenuse => sin 68 = 14 over x x times (sin 68) = 14 x = 14 over sin 68 x = 15.1 or 15.10 depend on how much they want you to round (15.099)
