Answer:
96°
Step-by-step explanation:
The measure of arc EC is twice the measure of ∠DEC, so is ...
arc EC = 2×68° = 136°
The measure of arc BC is found from the sum of arcs around a circle.
BC +CE +EB = 360° = BC +136° +128°
BC = 96° . . . . . subtract 264°

Answer:
1/2
Step-by-step explanation:
Pick two points on the line
(2,0) and (4,1)
Use the slope formula
m= (y2-y1)/(x2-x1)
= (1-0)/(4-2)
= 1/2
