Do you understand that the hypotenuse is always the longest sides in a right triangle and that it is opposite the right angle?

  • anonymous
yes I understand
Mertsj
  • Mertsj
So I repeat my original question: In relation to the angle x, what two sides do you know?
Mertsj
  • Mertsj
dang, buddy, the triangle only has 3 sides. If it's not the hypotenuse, what is left?

  • anonymous
I know sorry my screen froze I guess adjacent and opposite
Mertsj
  • Mertsj
Which is the adjacent side: 11 or 33? Remember adjacent means "next to"
anonymous
  • anonymous
33
Mertsj
  • Mertsj
Now, you know the adjacent side and the opposite side, what trig function does that make you think of?
anonymous
  • anonymous
tan right?
Mertsj
  • Mertsj
yes
Mertsj
  • Mertsj
\[\tan x=\frac{opp}{adj}\]
Mertsj
  • Mertsj
Fill in the sides and solve the equation for x

I got 0.00581 ? ...
Mertsj
  • Mertsj
What did you get for the tangent?
anonymous
  • anonymous
that's what I got I put tan 11/33
Mertsj
  • Mertsj
\[\tan x=\frac{11}{33}=\frac{1}{3}=.3333333...\]
anonymous
  • anonymous
how did you get the last part?
Mertsj
  • Mertsj
What do you think 1 divided by 3 is?

ohhh ok nvm >_<
Mertsj
  • Mertsj
So type .33333333 into your calculator and then push the inverse tangent button
Mertsj
  • Mertsj
Or, depending on your calculator push inverse tangent button and then .33333333 =
Mertsj
  • Mertsj
What did you get?
anonymous
  • anonymous
okay im using this calculator because I don't have one and still doing that I get the same answer .. http://web2.0calc.com/
Mertsj
  • Mertsj
Push 2nd Then the tan button will say atan which stands for "arctangent" Then enter .3333333333 Then push =
