Okay, so remember that the angles of a triangle are going to add up to 180. What's 95+62 ? Take than answer and subtract it from 180 and let me know what you get

Lars:

95+62 is 157, 157 - 180 is -23

So, we're going to write it as 180-157 and we will get a positive 23 because our angles aren't going to be negative. Other than that, you got it (:
