Answer:
70
Step-by-step explanation:
I would do 40 + 30 = 70
180-70 = 110
110 is the last angle bc all angles add to 180 in a triangle
Then 180 - 110 = 70 for angle 1 because their supplementary
I don't know if you could just add the 2 inside angles but I would do it this way to be safe until I know for sure.
If we take for example 20x1.5=30 the scale factor would create an enlargement
The point-slope form:

m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).
