Answer: FEATHERS!!!
Explanation: BOAS, HEAD DRESSES, FLUFFY DRESSESSSSS
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

Weaknesses include but are not limited to
-a weak central gov't
-political confusion
- differing philosophies
-communist society
-gender inequality
-social division "caste system" (but it could also be a strength in the sense that everyone knew their place"
You would first subtract 2 and 15 from both sides so you'll get -(3x+5)= -9 and then the negative would go into the 3 and 5 so it would be -3x-5 = -9 and then you'll add 5 to both sides then divide -3 to both sides so you'll get
but since 2 negative make a positive your final answer is
