you have to be more specific
which one is the hypotenus?
which ones are the legs. if you have a picture of the triangle use soh cah toa. sine- opposite over hypotenuse cosine- adjacent over hypotenuse tangent- opposite over adjacent
leave more info though

Law of Sines: a / (sinA) = b / (sinB) = c / (sinC)
(11) / (sin34) = (7) / (sinB)
sinB = 0.3559
B = 20.8, or 21 degrees
All angles in a triangle add up to 180 degrees, so A + B + C = 180
(13) + (24) +C = 180
C = 143
Use law of sines:
(5) / (sin13) = c / (sin143)
c = 13.38

be more specific, but ill tell you what i think the answer is, about 24 by using law of sin, but it is possible to get different answers by using tan and cos becasue you were not that specific hope this helps

Hans all your questions involve the law of sines. Use it!!!
It is certainly in your math book.

Not enough information given for either.
Where is angle A? Where is angle B?
Is a from A-B or A-C?
is b from B-A or B-C?
is c from C-A or C-B?

Your question leaves too much to guess at in re to what is where.

use trigonometry to find it.
