Suppose that 16 inches of wire costs 80 cents.
At the same rate, how many inches of wire can be bought for 45 cents?

12cm

the answer is d

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
