Answer:
2/1 or 2
Step-by-step explanation:
the way to find the slope is rise over run, if you count the units you see that for every time it rises 2 it runs 1, then divide.
19°
Set up the equation (triangles add up to 180 degrees)(Right angles are 90 degrees).
39 + 90 + 2x + 13 = 180
142 + 2x = 180
2x = 38
x = 19
