Need questions so we can answer it
1st, let's calculate the side AB = c in applying the law of cosine:
AC² = BC²+AC² - 2AB.BC. cos87°)
c²= 10.1²+9.8²-2(10.1)(9.8)(cos(87)
c²=102.01 + 96.04 -196.96cos(87)
c² = 187.74 and c = 13.7
Having calculated the 3rd side, now we can apply Heron's formula for the area:
AREA = √p(p-a)(p-b)(p-c), where p is half the perimeter or p=(a+b+c)/2 =16.8
AREA = √16.8(16.8-10.1)(16.8-9.8)(16.8-13.7)
AREA = 49.42 OR 49.4 unit²
I think the insurance that they should purchase is: C. supplemental insurance
Dental insurance is not covered by Medicare, so both HMO and Point of service is out of the option.
I think supplemental insurance will be the best option because it is the type of insurance sold by private companies that specifically cover the policies that are not covered by normal Medicare.
B. Runs his dishwasher only when it’s full.
All the rest seem like ways to waste water so I think B makes the most sense
