From one vertex of an octagon you can draw 5 diagonals.
There are 8 vertices in an octagon, and we are choosing one as our starting vertex. There are then 7 vertices left to draw a line to, but 2 of the vertices are already connected to our main vertex (because they are connected along the side of the octagon). That leaves 5 vertices to draw a diagonal to from our original vertex.
Answer:
I believe that the answer is 'n=8'.
#7 is the easiest one.
a + bi = -9 + 4i
see the expression on either side matches up so..
a = -9 and b = 4
Answer:
5
Step-by-step explanation:
I am not quite sure if this is correct.
first I figured out how many minutes per 1 mile: 24
then I figured out how exactly much time 1.5 hours is: 1 hour and 12 minutes. then I subtracted that from 2 hours, knowing that 1.5 hours is 3 miles, I found that there was only 48 minutes remaining in that hour, which would be 24×2, aka 2 miles. so the final answer would be 5 miles, sorry for the run-on sentence. Yet again, I am not quite sure if this is right-
