120 degrees

Step-by-step explanation:

First, you need to find the measurement of the angle that is supplementary to D.

To do that you do 180-130=50, we know this is true because the two angles make a straight line.

Then you can find angle 2 because we have two of the angles in the triangle. All triangles have measurements of 180, we can use this information by doing

180-(50+70)=60, so angle 2 equals 60, then to find angle 1 you do

180-60=120, because they make a straight line.

angle 1=120
