Answer:

the cosine of the angle equals 40.0 m divided by the length of the wire

cos(58º20') = 40.0 m / L

L = 40.0 m / cos(58º20')

Using logarithms property of log(x)+log(y)=log(xy)
so here, you can sum the equation to;
log((x+6)*(x-6))=2
so you can simply say that;
log_{8}((x+6)( x-6))=2
and by multiplying (x+6)*(x-6)
log_{8}(x^2-36)=2
and as you know also that;
a^{b}=c is same as log _{a}c=b
so you can simply state it as;
8^2=x^2-36&#10;64=x^2-36&#10;64+36=x^2&#10;x^2=100&#10;x=10
And you can check your work by substituting with 10 instead of x in the original function.
Hope this helps!
