can somebody match these three I ned help very bad in math!! Please help Given shown below, match the trigonometric term on the left with its corresponding ratio on the right. Match Term Definition 1. sine ∡B A)36/85 2.cosine ∡B B)77/85 3. tangent∡B C)77/36
is it 4B or 48?
don't you have a diagram?
huh?
i'll draw it out for you
Actually, I don't need a diagram. It can be figured with logic and no drawing. tan = c, sin = b, cos = a.
thank you :D as you can tell i'm really terrible at math
But we need to go thru this.
Just me giving you an answer is not going to help you at all, so let's go thru it, ok?
|dw:1348423615862:dw|You have lengths 36, 77, and 85 and a bunch of trig questions, so it looks like these lengths form a right triangle, so taking the 2 smallest numbers, we get 36^2 + 77^2 and checking, we see that it does indeed = 85^2. So, we must have (see drawing). It turns out that we have the second drawing by trying the tan. With me so far?
The rest is easy. Just evaluate sin and cos.
|dw:1348424023928:dw|The only thing I needed to add to the drawing is the angle B.
Are you still there? It would be helpful for you to go over this drawing and the logic. Otherwise, you will not have learned anything.
im back now @tcarroll010
