The y intercept will be at (0,9), the slope will be -1/1, which means go right one, down one. Draw the line connecting the points and then arrows on either side of the line.
Use law of sine, sinB/AC=sinC/AB
sin122/10.2=sinC/6.8
sinC=sin122*6.8/10.2
use your calculator: C=34
Please use your calculator to double check my numbers.

Answer:
115
Step-by-step explanation:
115 cannot go into 15 evenly. The closest you can get is 7.
If I've understood your question, you're asking about this:

A number raised to a negative power is the same as the inverse of that number raised to the positive power. Basically the number moves from the numerator to the denominator or the denominator to the numerator. So 1/(3^-2) is the same as 1 / (1/3^2), which is the same as 3^2. That means what you have here is 4 x 3^2, which is 36.
