a pentagon has sides 2N+7,3N+2,6,7N,5N-6.If the perimeter is 180,find the length of each side.
add up all the like-terms... you get:
17N + 9 = 180
17N = 171
N is about 10.
Then plug 10 in for N and solve for each length
17N + 9 = 180
17N = 171
N is about 10.
Then plug 10 in for N and solve for each length
