You add all numbers and it will equal 99
Hello,
Shall we begin?
<span>8(4k-4)=-5k-32
</span>32k - 32 = - 5k - 32
32k + 5k = -32+ 32
37k = 0
k = 0
Answers: k=0
Can't see the work send a Bette pic or write the question
Octogon
sides=4
draw lines from the outside angles to the center so they form 8 equal triangle sections
find the area of each triangle and multiply by 8
area of triangle=1/2 base times height
base=4
the height is the distance from the center of one side of the octogon, to the center=5
so area=4 times 1/2 times 5=4 times 5=10
8 triangles so 8 times 10=80
the answer is 80cm^2
the diagram included below shows area for a pentagon
The answer is C,
Coterminal when involving angles is an angle that is 360 degrees greater or lesser. In order to find whether something is coterminal or not you take one of your angles and subtract or add 360 from it until you reach that number. If you add/sub 360 and you can't ever equal the other number than they are not coterminal.
Example:
591 - 360 = 231
So that means
231 degrees = 591 degrees
Example 2:
51 - 360 = 309
51 + 360 = 411
411 + 360 = 771
771, 411, and 309 /= 591 or 231
So 51 degrees /= 231 or 591
C: 51 is not coterminal!
Hope this helped!
