-30 = -16 + N what is he answer to this
1 answer:
Answer:
Step-by-step explanation:
To solve for the given variable , we need to get
on one side of the equation by itself. To do so, we need to remove the -16 that is on the same side of the variable.
To get rid of the -16, we can add a 16 to that side of the equation since , which will get
by itself; however, if we add -16 to one side of the equation, we must add it to both sides of the equation:

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:
