Answer:
X is your answer bc when coordinates are flipped over the x-axis the y coordinate goes negative
The answer is 4.5 for the side length of the pentagon and 7.5 is the side length for the triangle because 7.5*3(3 sides) = 22.5 and 4.5*5(5 sides)= 22.5. The perimeter is 22.5
The answer is: <span>t=17.5 and f=12
