Answer:
90degrees
Step-by-step explanation:
To get the measure of angle C, we will use the cosine rule as shown;
AB² = AC²+ BC² - 2(AC)(BC)cos C
85² = 13²+ 84² - 2(13)(84)cos C
7225 = 169 + 7056 - 2184cosC
7225 - 7225 = -2184cosC
0 = -2184cosC
cosC = -0/2184
cosC = 0
C = arccos0
C = 90degrees
Hence the measure of angle C is 90degrees

Answer:
$2104.36 fixed expenses
$save 209.71 per month
Step-by-step explanation:
985.64+58.30+(2)(154.00)+180.00+128.40+(4)(55.00)+(684.80/6)+(330.00/3) = 2104.36 monthly expenses
2943.20-2104.36 = 838.84
838.84 x 0.25 = 209.71
