Nonagon - 9 sides
Sum of interior angle of a polygon is (n-2)180 = x
N is the number of sides, so when you plug in 1260 for x, you get 9 for n
Answer:
-189.8 J
Step-by-step explanation:
We are given that f
Force applied=F=35 Ni-37 Nj
Displacement, s=(-8.7m)i-(3.1m)j
We have to find the work done .
We know that
Work done=
Using the formula
Work done=
Work done=
Using 
Work done=-189.8J
Hence, the work done =-189.8 J
Answer: 12
Step-by-step explanation:
6c + 11= 2c + 59
Collect like terms
6c - 2c = 59 - 11
4c = 48
c = 48/4
c = 12
Direction: Isolate the variable by dividing each side by factors that don't contain the variable.
