Answer:
D
Step-by-step explanation:
Pluck in the values, we have:
4.5/2.4 - 6 = 20/2 = 10
Given:
angle ECB=51 degrees
=>
angle EOB = 2*angle ECB = 2*51 = 102 degrees = arc EAB
Also given minor arc AB = 72 degrees
therefore
minor arc EA = 102-72=30 degrees
Yes it tells how much or how less
D: {-3,1,2,3}
R: {-4,0,1,2}
