The rule for the angle formed outside of circle by intersection show below is given by:
Angle formed outside=1/2(difference of intercepted arcs)
∠ACE=1/2(AE-BD)
∠ACE=53°
AE=233°
BD=x
Hence the formula for obtaining BD will be:
53=1/2(233-x)
The correct answer is A
Answer:
y=-x-9
Step-by-step explanation:
y-y1=m(x-x1)
y-0=-1(x-(-9))
y=-1(x+9)
y=-x-9
Answer:
See step-by-step explanation
Step-by-step explanation:
16. C, <AOB = 20
The total angle (<AOC) is equal to the sum of the angles inside of it (<AOB and < BOC).
<AOC= <AOB + <BOC
47=<AOB+27
<AOB=20
17. 24
Area of a square = 
36= 
s= 6
One side is 6
The perimeter of a square is 4(s)
4(6) = 24
Word of encouragement:
Good luck!
If one ratio is equivalent to another, that means that you multiply the top and the bottom on one ratio by a constant to get the larger ratio. D does that here for us. We have to multiply 3 by 5 to get to 15, so 16 times 5 better be 80 and it is.
