Answer:

50 degrees

Step-by-step explanation:

By the Law of Cosines,

6² = 7.5² + 6.5² - 2(6.5)(7.5)cos C

6² - 7.5² - 6.5² = -2(6.5)(7.5)cos C

-62.5 = -97.5 cos C

cos C = (-62.5)/(-97.5) = 25/39

C = arccos(25/39), which is about 50°

Answer:

$43,260

Step-by-step explanation:

You have the 3% annual income, which you can convert to a decimal. This gives:

42000 * 1.03

42000 represents Blair's initial income, and 0.03 represents the 3% increase.

I chose 1.03 because I don't have to subtract 97% and add it to 42000.
