PLEASE HELP ME!The sail of a boat is in the shape of a right triangle, as shown below. Which expression shows the length, in meters, of the side adjacent to the 50 degree angle?

Sure, let me try

Are you familiar with SOH CAH TOA? SOH - opposite / hypotenuse CAH - adjacent / hypotenuse TOA - opposite / adjacent

You are given the angle, 50 degrees, and the length of the opposite side from the angle, which is 6m
anonymous
  • anonymous
yes
anonymous
  • anonymous
Therefore, what trigonometric relation do you think you should work with, given that you want to find the length of the adjacent side for the angle
anonymous
  • anonymous
Which two sides do you have work with relative to the angle 50 degrees?
anonymous
  • anonymous
im not sure
anonymous
  • anonymous
All right, let's figure it out. You have 3 sides, can you identify the hypotenuse in the picture?

You know that it is a right triangle, because there is a 90 degree angle at the bottom left of the triangle
anonymous
  • anonymous
the longest side
anonymous
  • anonymous
Cool, which is which side? The left side, the bottom side, or the right side?
anonymous
  • anonymous
In a right triangle, 90 is the large possible angle, and in triangles, the largest side is opposite the largest angle

the left ?

The left is the side that is 6m, that is the one you mean?

Cool, from the picture I drew, you're saying 'CB' is the hypotensue?
anonymous
  • anonymous
yeah
anonymous
  • anonymous
Right on, that's it! So in the picture of the sail, the hypotenuse is the right side, just like in the drawing
anonymous
  • anonymous
Now, can you tell me what the functions of angle B are in the drawing, use the line segments like you just did to identify the hypotenuse. sin(b) = ? cos(b) = ? tan(b) = ?
