Use graphs and tables to find the limit and identify any vertical asymptotes of the function.

You have not provided a function, however, normally when the instructions say to use graphs, you just need to graph it in your calculator and then take a look at it to see what the limit will be at the requested x value. Remember to write your asymptote as a linear equation once you identify it from the graph. 

The answer is D, 110 degrees. The angles mirror each other.
