Answer:
6
Step-by-step explanation:
anything over 5 you round up.
7 is greater than 5 so you round up to 6
Answer:
41
Step-by-step explanation:
41
Answer:
1. diagrams C. D. and F. are adjacent angles, which are angles that share a vertex and side
2. diagram B. are vertical angles
3. diagram A. are complementary angles
4. diagram E. are supplementary angles
5. diagram D. is a linear pair
Remark
I'm so glad you got a good answer to the central angle problem. Geometry can be that way. What I did was correct and would have worked with any two arcs, but a wonderful answer you got from the other responder.
This problem uses the fact that from an external point, when two secants are drawn (as in your diagram) the difference in the arc sizes divided by two gives the angle between the secants (in this case 23).
Formula
Angle between secants = (large arc - small arc)/2
Givens
Angle between secants = 23
The small arc = 77
The large arc = x
Sub and solve
23 = (x - 77) / 2 Multiply by 2
23*2 = (x - 77)
46 = x - 77 Add 77 to both sides.
46 + 77 = x
123 = x Answer
Since he started with Nothing
He had zero initially
After x Months...
He'll have 10x naxvips
in slope intercept form
y=10x
To get the y values ... substitute the corresponding x value
For x=0
y=10(0)
y=0. Which is true cos he had no naxvip initially
x=1
y=10(1)
=10. Which is true cos he buys 10 more monthly... So 10 + 0 = 10.
x=2
y=10(2) = 20. This is true cos he added an additional 10 after each month
x=7
y=70.
