# How do you solve a triangle ABC given A= 30 degrees, B= 45 degrees, a= 10?

First calculate the third angle by subracting:

Then, you know that in any triangle is true that (Euler theorem)

so use:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- When can the law of sines be used?
- A triangle has sides A, B, and C. Sides A and B have lengths of 2 and 3, respectively. The angle between A and C is #(13pi)/24# and the angle between B and C is # (3pi)/8#. What is the area of the triangle?
- If #A = <3 ,1 ,-1 >#, #B = <4 ,6 ,-1 ># and #C=A-B#, what is the angle between A and C?
- If sides A and B of a triangle have lengths of 12 and 2 respectively, and the angle between them is #(3pi)/8#, then what is the area of the triangle?
