Answer:
Step-by-step explanation:
Suppose we have a general triangle like the one shown in the figure.
We know the angle A, the angle B and the length b.

By definition I know that the sum of the internal angles of a triangle is always equal to 180 °.
So

We solve the equation and thus we find the angle C.

We already know the three triangle angles.
Now we use the sine theorem to calculate the sides c and a.
The sine theorem says that:

Then



Also



Finally, we use the Heron formula to calculate the triangle area

Where s is:

Therefore
