|dw:1405296514211:dw|  Where I have the question mark what would that angle be?

anonymous · Answer

I'm not sure how to find that angle. Other than simple formulas like A+B=90 or a non-right triangle should equal up to 180 degrees. If you could guide me, I'd really appreciate it.

anonymous · Answer

A straight line equals 180 degrees |dw:1405296854061:dw|  So what would the ? be?

anonymous · Answer

155 degrees?
