|dw:1329765647534:dw| is that your question?

anonymous · Answer

Yes it is.

anonymous · Answer

okay it can be rewritten as |dw:1329765756874:dw| does that help?

campbell_st · Answer

$$\tan B = \pm 2$$ since B is between 0 and 90 just find arctan (2)

anonymous · Answer

campbell is right I was just trying to lead you down that path instead of giving it to you

anonymous · Answer

One thing I feel nesscary to mention is this|dw:1329765918164:dw|

anonymous · Answer

thats to the negative one it cut off my drawing for some reason

anonymous · Answer

So when it says to find it to the nearest degree. You do the arctan of 2 which is 63.4349. So my anwser will be 63 degrees?
