Answer:
7
Step-by-step explanation:
Assuming the shapes are similar then x would equal 7. If two shapes are similar then the length of their sides should be proportionate. They will also have a scale factor, which is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure, so the number a side is multiplied or divided by to get the corresponding length. In this case, the scale factor is 11. We know this because 88/11=8. So to find x just divide 77 by 11 to get 7.
