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
Answer:
well the Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.
Explanation: i tired my best i hope this answer your question. if this is wrong i am very sorry
I don't see the picture so i can't answer your question
Answer:
512
Explanation:
8 cubed is written as 8 to the power of 3 or 8*8*8
which is 8 times 8 times 8
let's break it down
8*8 = 64
64*8=512
final answer: 512
to check, do the opposite of what you just did
take the cubed root of 512
and you'd get 8
