Answer:

Step-by-step explanation:
-2(x+3)=-10
There are two ways to approach solving this problem
1. You can distribute -2 to each term in the parentheses
-2x -6 = -10
OR
Divide each side by -2
2. -2(x+3)=-10
-2/ -2 (x+3) = -10/-2
x+3 = 5
They will both result in the same answer at the end
Use the cosine rule.
c=AB=7
b=AC=8
a=BC=3
a^2=b^2+c^2-2bc(cos(A))
=>
cos(A)=(b^2+c^2-a^2)/(2bc)
=(7^2+8^2-3^2)/(2*7*8)
=13/14
=0.9286
