Step-by-step explanation: In order to solve you would typically need to find a protractor. For 1, all you need to do is subtract the other angles listed from 360 degrees and then divide. If I were you, I would download a protractor from the app store. Try exysoft, that's the one i use. To make sure you are correct, add all your answers together and make sure it adds to 360. Hope this helps a bit
