Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + y² = z² , substitute values
4² + y² = ( )², that is
16 + y² = 137 ( subtract 16 from both sides )
y² = 121 ( take the square root of both sides )
y = = 11 → D
