The sum of the three angles of the triangle must be 180 degrees. If two of the angles are 30 and 70 (which adds up to 100 degrees), what would you have to add to 100 degrees to get 180 degrees? You can probably figure this out in your head, right? Did you get 80 degrees? Does it check? Does it all add up to 180 degrees?
