How many diagnols can fit in a 8 sided shape?

Mathematics
1 answer:
Jobisdone [24]3 years ago
8 0

Drawing a diagonal means to connect a vertex with another non-adjacent vertex.

So, for each vertex, we have 8-3=5 possible diagonals. This leads to a total of 8*5=40 diagonals.

We have to divide this number by 2 though, because in this way we're counting each diagonal twice (connecting points AB or BA gives the same diagonal).

So, an 8 sided shape has 20 diagonals.

What is -5/8÷9/10=========
k0ka [10]

Answer:  -25 / 36

Solution:

Step 1: Lets flip the division sign to multiplication

Note : when the sign is reversed, the second term in the equation will have the numerator and denominator swapped  

-5/8 ÷9/10  > > > > > > -5/8 * 10/9

Step 2 : so it will be  

-5/4 * 5/9 when simplified,  which would be -25 / 36 > > > > >  - 0.69

Hope this solution will help you understand the problem and don't forget the negative sign it may cost you marks :)
