To solve this problem you must apply the proccedure shown below:
1. You have that:
- T<span>he equation d=1/2(n(n-3)) gives the number of diagonals for the polygon.
- The polygon that has 65 diagonals..
2. When you clear n, you obtain:
d=n(n-3)/2
d=(n^2-3n)/2
2x65=n^2-3n
n^2-3n-130=0
3. When you solve the quadratic equation, you obtain:
n=13
Therefore, the answer is: 13 sides. </span>
Answer:
60
Step-by-step explanation:
using rise over run method, from (0,20) to (1,80) the line slants up by degree of 60 per one unit so the slope is 60.
The answer is a. (0,2) , (1,2), (2,3), (1,4) , (3,1)
this is because (x, y) . x is first then y
43568 x 32159 = 1,401,103,312
