the sum of the angles in an ngon (a polygon with n sides) is (n-2)*180
so an octagon has 8 sides and has a sum total of (8-2)*180=1080 degrees
if each of 7 angles is 132, then 1080=?+7*132
1080=?+924
156=?
the 8th angle is 156 degrees
Answer:
see explanation!
Step-by-step explanation:
Line N
- A set of points where the coordinates of each point have a sum of 2
Line M
- A set of points where the y-coordinates of each point is 10 less than its x-coordinate
Any coordinate on N has a sum of 2.
Any coordinate on M has a y that is 10 less than the x.
Answer:
1. A. 4 terms
There are 4 different values in the expression, so therefore there are 4 terms.
2. D. 3x^2 + 6x + 10
To get the answer...
start with the original expression: 3x^2 + x + 10 + 5x
add the like terms together, in this case you'd add x + 5x
you'll get: 3x^2 + 6x + 10
I hope I could help :)
If one book = 1/8, then you can just multiply it by 3, for the three mystery books. 8x3= 24, so tony has 24 books in all.
Answer:
5
Step-by-step explanation:
because 5*5=25 and you have 1 remainder
