In order to find supplementary angles you have to find angles that add up to 180 degrees, which is a straight line.
Just find the vertex and then compare with graph
#a
Parabola opening upwards
Graph 3
#2
Vertex at (-3,0)
Graph IV
#3
Parabola opening downwards as a is -ve
Graph I
#4
One graph is left
1/3 into a decimal is 0.333.....
Answer:
m1 = 118 degrees, because it is a reflection of the other side of this line. m2 will be 180-118 = 62. This is because a straight line is always 180 degrees.
Therefore,
m1 = 118 degrees
m2 = 62 degrees
