Answer:

63°

Step-by-step explanation:

The sum of all interior angles of a triangle = 180°

Therefore:

x + 96° + 21° = 180°

x + 117 = 180

Subtract 117 from each side

x = 180 - 117

x = 63°

Solve for x by cross multiplying then isolating the variable:
$\frac{9}{15}= \frac{x}{10}$ cross multiply
15x=90 Isolate the variable
x=6
Solve for y by cross multiplying then isolating the variable:
$\frac{9}{15} = \frac{6}{y}$ cross multiply
9y=90 Isolate the variable
y=10
