Answer:
129 degrees.
Step-by-step explanation:
As we can see, angle DCF is made up of 2 different angles, DCE and ECF, the sum of the measure of these two angles is equal to the measure of angle DCF.
75+54=129 degrees
Hope it helps!
B I think.correct if I’m wrong
Answer:
y=-3x+4
Step-by-step explanation:
im assuming that you need the equation of the table
to find slope, y2-y1/x2-x1 10-4/-2-0
6/-2=-3 slope=-3
y=mx+b just sub in the numbers from a point in the table
10=-3(-2)+b
10=6+b
b=4
y=-3x+b
