The Law of sines / geometry: solve WXY, with m(w) = 38,....

[keri__lynn]

Iam also very lost on this question and need to be worked all the way out ....

solve triangle WXY. round the measures to the nearest tenth.

m<w=38, m<y=115, W=8.5

Re: The Law of sines / geometry

The first step is to write the law of sines (for this triangle WXY)

For triangle ABC , wth sides a, b & c( Usual convention of 'a' being opposite to angle BAC, or angle A),
we can write law of sine as

\(\displaystyle \frac{\sin(A)}{a} \, = \, \frac{\sin(B)}{b} \, = \, \frac{\sin(C)}{c}\)

What will be the corresponding equation for triangle WXY?

What are the known parameters (known values) for this triangles?

What are the unknown parameters for this triangles?

Write these out and tell us where you are stuck.

You already have completely-worked-out examples in your textbook and in your class notes (plus whatever parts of your homework "soroban" has done for you). If you are still utterly unable even to guess how to just get started, then you need much more help than we can here provide. Sorry!

Please seriously consider hiring a qualified local tutor and setting aside an hour or two a day for concentrated study sessions. By work with you face-to-face, your tutor will be able to examine your book, review your class notes, scan your course materials and handouts, and determine how far back to go to be able to start where you are comfortable. Then your tutor can re-teach the missing weeks or months of material, so that you can get caught up with your class. :idea:

My best wishes to you in your studies.

P.S. Or, if you were just exaggerating your confusion, please reply showing what you have tried and how far you have gotten. It would probably help if you started with an explanation of how your book is labelling things, since it looks as though W, X, and Y are the sides of the triangles (since they have lengths), but triangles are customarily defined in terms of their vertices (where the angles would be). Thank you!
