Answer:
30°
Step-by-step explanation:
Line AB and BC are tangents to the given circle.


Alternatively, <ABC and <AOC are supplementary because AB and BC are tangents.


The correct choice is A.
Answer:
y = -1/2x +1
Step-by-step explanation:
The y intercept is 1 (this is where it crosses the y intercept)
(0,1) and (2,0) are two points on the line
The slope is given by
m = (y2-y1)/(x2-x1)
= (0-1)/(2-0)
= -1/2
The slope is -1/2
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
y = -1/2x +1
Answer:

Step-by-step explanation:
The probability for a flip on either side of the coin is always 50% or 
So to get the probability for the three flips just do:
or
×
× 
Either way you solve it the answer is 
Answer:
The diameter would also double
Step-by-step explanation:
1 plus 2 = 3, then u do 6/2 (3), then 3x3 = 9
