Answer:
see the attachments
Step-by-step explanation:
Actually, the given description fits 3 different triangles. They differ in the size of the included angle, hence the length of the remaining side. Possibilities are ...
_____
When the non-included angle is opposite the long side, there is only one solution to the triangle. (See the first attachment.)
When the non-included angle is opposite the shorter of the given sides, there are generally two possible solutions. One of these has an acute angle opposite the long side; the other has an obtuse angle opposite the long side.
In any event, the Law of Sines is used to solve the triangle. First, the angle opposite the other given side is found; then the remaining angle and the side opposite it.
Suppose the given sides are "a" and "b", and the given angle is A. Then the Law of Sines tells you ...
B = arcsin(sin(A)·b/a) . . . . . possibly 2 values
From which ...
C = 180° -A -B
which allows finding ...
c = a·sin(C)/sin(A)
