Answer:
180 degrees
Explanation:
Since the angles of a triangle will always be 180 you just have to find the other angles. You already know that one is 34 degrees, but the angle that is 140 degrees is a supplementary angle becuase if you see the bottom line it is straight and that means that you can make 140+x=180 and if you subtract 140 from both sides you know that the inside angle equals 40 degrees. If you add 34 and 40 together you get 74 and when you subtract that from 180 you get 106 so that means the measure of angle 1 is 180 degrees
