Look at the picture. The angle is 34 degrees, right? I would replace θ with 34 in your equation sin(θ) = Opposite / Hypotenuse which side is opposite (look at my picture) how long is it?

90 is an angle (the right angle) the sides are the lines. I drew an arrow pointing at the line opposite the 34 degree angle

34 is an angle. remember that you want the legs (the sides of the triangle)

phi Group TitleBest ResponseYou've already chosen the best response.1
and we need to use trig here. pythagoras needs 2 sides (and no angles). But here we know 1 side and 1 angle. so we use trig. what is the length of the side opposite the 34 deg angle. look at the picture.

phi Group TitleBest ResponseYou've already chosen the best response.1
yes. you replace opposite in sin(θ) = Opposite / Hypotenuse with 18. you replace θ with the angle 34 can you do that?
 2 years ago

phi Group TitleBest ResponseYou've already chosen the best response.1
pay attention: 34 is an angle. sin(θ) = Opposite / Hypotenuse means that the sin of an angle is opposite leg/ hypotenuse sin(34)= 18/x x because the picture calls the hypotenuse x now you need to solve for x can you do that ?

its 32.1 ! :DDDD

phi Group TitleBest ResponseYou've already chosen the best response.1
just for info: If you are given 1+a and are told: replace a with 2, you would write 1+2 if your are given a/b and are told replace b with 3, you would write a/3 you need to do this "replace" to use these equations.

if you have time, this video http://www.khanacademy.org/math/trigonometry/v/basictrigonometry might be helpful. It helps me to see someone do the steps.
