How to solve this triangle C = 114, b = 26, c =21 degrees When I use Law of Sine \( \frac{\sin114}{22} = \frac{\sin B}{26} \) I get 1.0796 Am I doing this right?

OpenStudy (anonymous):

Sorry c = 22

OpenStudy (anonymous):

Note, C = 114 degrees and b and c are sides.

OpenStudy (jack1):

i think u have it mixed up?

OpenStudy (jack1):

ah, ok?

OpenStudy (abdullahm):

That makes more sense because you put degrees after the little c and that confused it all.

OpenStudy (abdullahm):

That doesn't make a triangle though...?

OpenStudy (abdullahm):

Are you sure that the numbers you have provided are correct?

OpenStudy (jack1):

usual notation is capital letters are side lengths and small / lower case letters are angles...

OpenStudy (anonymous):

Yes the numbers are right. Also, my book has Angles as capital and sides as lower case.

OpenStudy (abdullahm):

So to make sure, you have Angle C = 114 degrees Side c = 22 units Side b = 26 units ?

OpenStudy (anonymous):

All I did is bump the numders up 1, but my original problem I still get sine being over 1

OpenStudy (abdullahm):

Angle C is the largest angle, so it has to have the largest side length, which is not the case. So it can not form a triangle.

OpenStudy (anonymous):

AbdullahM that is correct

OpenStudy (anonymous):

the origninally problem is C=113 degres b =25 and c = 21 but sine is still over 1

OpenStudy (abdullahm):

That still doesn't form a triangle, however.

OpenStudy (anonymous):

So I take it there is no triangle.

OpenStudy (anonymous):

That must be the solution. There is no triangle.

OpenStudy (anonymous):

That is what I get.

OpenStudy (abdullahm):

That should be the answer as no triangle can be formed with given measurements.

OpenStudy (abdullahm):

|dw:1434811264905:dw| It simply isn't possible.
