For this case, using the law of cosine we have:
c ^ 2 = a ^ 2 + b ^ 2 - 2 * a * b * cos (C)
Substituting values we have:
c ^ 2 = 10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105)
Clearing c we have:
c = root (10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105))
c = 14.33216827
round the answer to the nearest tenth:
c = 14.3
Answer:
the length of side c is:
c = 14.3
Closure property: If a and b are real numbers, a+b is also a real number.
- Associative property: a+(b+c) = (a+b)+c.
- Commutative property: a+b = b+a.
- Additive identity: a+0 = a.
- Additive inverse: a + (-a) = 0.

<h2>
The value of A + b + c = - 9</h2>
Step-by-step explanation:
We have,
A + b + c and
A = 4, b = - 5 and c = - 8
To find, the value of A + b + c = ?
∴ A + b + c
Put A = 4, b = - 5 and c = - 8, we get
= 4 + ( - 5) + ( - 8)
= 4 - 5 - 8
= 4 - (5 + 8)
= 4 - (13)
= 4 - 13
= - 9
∴ The value of A + b + c = - 9
