*73 POINTS AND BRAINLIST* what is the value of x in these polygons?

x = 9

y = 27

Step-by-step explanation:

Sides are in the ratio 4:3

(16:12 & 32:24)

4/3 = (x-1)/6

24/3 = x-1

x = 8+1 = 9

4/3 = (y+1)/21

4×21/3 = y+1

28-1 = y

y = 27

Step-by-step explanation:

This implies that;

We then multiply both sides by 6 to obtain;

Now, group similar terms to get;

Thus, the value of x is = 9.
