Answer:
Complementary angles are two angles that have a sum of 90°.
Supplementary angles are two angles that have a sum of 180°.
A ABC BCD SUPP 90+90=180
B BCA ACD COMPL 45+45=90
C BCA CDA NEITHER 45+90=135
D ABC CDA SUPP 90+90=180
E BAC CAD COMPL 45+45=90
Step-by-step explanation:
Answer:
x = 80
Step-by-step explanation:
Both angles together form 180, therefore x is 80
Answer:
y=-3x-1
Step-by-step explanation:
We can calculate the slope of this line:
Slope = (y2-y1)/(x2-x1) = (-4-2)/(1-(-1)) = -6/2 = -3
We can pretty much stop here and say B is correct.
Answer:
Infinity
Step-by-step explanation:
Because there are lots of ways
