52=100%
x=30%
52/x=100%/30%
which equals to 15.6
Answer 15.6
For this case we have the following functions:

We must find
. By definition we have to:

So:

Finally, the composite function is:

Answer:

80 degrees. 145 = (4x+5) + (6x-10) = 10x-5... so 10x = 150, x = 15. LMN = 6x-10 = 6(15) - 10 = 80.
