A pentagon is shown with sides labeled 5 in., 5 in., 7 in., 7 in., and x in.
The perimeter of this pentagon is 29 in. Which is the missing side?
A. 35 in.
B. 12 in.
C. 7 in.
D. 5 in.
We can start by adding up the known sides: 5 + 5 + 7 + 7 = 24. We know the perimeter is 29, so we can subtract 24 from 29 to get the missing side:
29 - 24 = 5
So the missing side is 5 inches. Therefore, the answer is D.
