|dw:1399586844393:dw| What is the value of x rounded to the nearest hundredth?
First of all tell me what you got here? Tangent,Sin or Cosine?
o.o ummmm tangent ?
mm great!.Now you got tangent 49=x/55 right?
because remember you're not looking for the angle this time,you're looking to a side.So it will be 49=x/55 x is the opposite and 55 the adjacent
you understand what I'm doing?
yes
so find now the tangent of 49
you have a calculator?
yes ... how do i do it ?

@Compassionate
I talked to you before and you took so long to answer just press where it says tan and put 49
-3.17 etc..
|dw:1399653213861:dw| Angle, side adjacent to angle...and want the opposite side....= tangent \[\large \tan\theta = \frac{Opposite}{Adjacent}\] \[\large \tan(49^{\circ}) = \frac{x}{55}\] \[\large x = \tan(49^{\circ}) \times 55\] @Gabylovesyou Make sure that your calculator in in "degree" mode...if you are getting -3.17 for your answer of tan(49) you are actually in "Radians" mode :)
