Best ResponseYou've already chosen the best response.0dw:1366585349856:dw \[\frac{35}{\sin(21)} = \frac{b}{\sin(101)} \rightarrow (35)\sin(101)=b \sin(21) \rightarrow \frac{(35)\sin(101)}{\sin(21)}\] which gives me 95.87.

Best ResponseYou've already chosen the best response.0I have one problem with this. How do you know that CB is perpendicular to the horizontalish line A? If you don't know that, you can't assume the 90 degrees or the 11 degrees via parallel lines+transversal.

Best ResponseYou've already chosen the best response.0I know that the pole is perpendicular because it does not say otherwise, and thus I drew the line parallel to the horizontal and created the 90.

Best ResponseYou've already chosen the best response.0Since that is not what I did, I certainly would not use similar logic.
