Answer:
X=63
Step-by-step explanation:
The quadrilateral above are similar and they have a ratio. To find the ratio divide a bigger side in the first shape by a corresponding smaller side in the other shape
36/4 = 9/1
The ratio is 9:1
When a side in the big shape is 9 the other shape is 1
Therefore x/7 =9
x = 7 * 9
=63
