Answer:

Step-by-step explanation:
By the theorem of intern angles of a triangle, we know that the sum of all intern angles of a triangle must be 180°, therefore:
*There are two equal angles because there are two equal sides

Now, applying the law of sines, we can find side a. The law of sines is represented by the following equation:

Hence, if b=100, alpha=40° and betha=70°, solve for a:
