Answer:

  • x = 6.6 inches
  • y ≈ 12.0 inches

Explanation:

The Pythagorean theorem relates side lengths in right triangles. It tells you the square of the hypotenuse is equal to the sum of the squares of the sides.

__

Left triangle

8.8² + x² = 11²

x² = 121 -77.44 = 43.56

x = √43.56 = 6.6 . . . inches

__

Right triangle

6.6² +10² = y²

43.56 +100 = y² = 143.56

y = √143.56 ≈ 11.982

y ≈ 12.0 . . . inches
