Question

Use RST to find the Sin R, Cos R, Tan R, Sin S, Cos S, Tan S. Express each ratio as a fraction and as a decimal to the nearest hundreth.

1. R=16, S=30, T=34

2. R=10, S=24, T=26

(For this questio I think the sides of the triangle are for RS Think it is the Hypotenuse for ST is the opposite leg TR could be the adjacent leg)

Find each trionometric ratio. Express answers as a fraction and as a decimal.(answers rounded to. Nearest ten thousanth.)

3. Tan= C
4. Sin A
5 Cos C

(For this triangle I think the sides are the following: AB is the opposite leg BC is the Hypotenus, AC Is the adjacent leg. And the numbers are for AB is nine BC is 40, and AC is 41)

Thanks in advanced

Answer 1

I assume you are talking about a triangle RST, where angle T is a right angle.

The measurements you give for R, S, and T don't make much sense in that case. You ask for sin(R), cos(R), sin(S), cos(S) and tan(S), which suggests that R and S are the acute angles of the triangle. But if that's the case, you can't use R and S and T to label the sides of the triangle as well!!!!

And clearly the measures given for R, S, and T are not angle measures, since they don't sum to pi/2 or 90 degrees.

There's something about the way you've stated this problem which just doesn't make sense.

I would suggest looking over the problem again, and being extra careful keeping track of which labels are used to describe points, which are describing angles, and which are describing sides. Perhaps the sides aren't even labeled with variables, but just with distances. In that case, you should state that side RS has length 10 (or whatever....)

Also, in your second problem you talk about which sides are the oposite leg and the adjacent leg. But the questions are asking for the tangent and cosine of C, and the sine of A. The leg opposite angle A is adjacent to angle C, and the leg opposite angle C is adjacent to angle A. There is no "opposite leg" or "adjacent leg" in a right triangle. The legs are only considered opposite or adjacent RELATIVE TO AN ANGLE!!!

I hope that helps clear some stuff up.

Perhaps this will be enough help that you'll be able to use SOH-CAH-TOA to solve the problems yourself now.

Good luck

Answer 2

You need to show a diagram; the question is not clear.

Answer 3

draw it out and you should find out the answer
plus, your descriptions are a bit confusing

Answer 4

i have noooo idea what you are talking about!
