Answer:
x = 17.5
y = 5
Step-by-step explanation:
Similar means that corresponding angles (same colors in this case) are the same. Rotate the 2nd figure on the right in your mind until the angle label colors fit the 1st figure, just so you can tell what's what. Then you can create ratios with corresponding sides that include only one of the unknowns. So 1st we use
x/7 = 15/6
x = 15/6 * 7
x = 17.5
and
y/12.5 = 6/15
y = 6/15 * 12.5
y = 5
