I might give brainleast depending on the answer

Hi!

So, i know for a fact that 2=30*, because it is the same length.

1 and 3 are the same way, but they are farther out. the answer tp 1 and 3 are not A or D, because that is lower than 90*, which is acute, not obtuse. Now its between B and C. Its not C, because its too far.
