Answer:
135°
Step-by-step explanation:
Since it's a right triangle, one angle will be 90° and the other given one is 45°. The total degrees in a triangle is 180 therefore ∠CAB is 45°.
Because ∠CAB is supplementary to ∠CAD, you have to subtract 180° -- since it's a straight line -- with 45°.
This gives you 135°

Answer:
A) 1/5
Step-by-step explanation:
Points on the graph: (10, 2) and (20, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4-2)/(20-10)
m= 2/10
m = 1/5
