Let's denote Kelly's height as \( h \). According to the information given, we can set up the following equation:
\[ h - 10 = 50 \]
To find Kelly's height, we can solve for \( h \):
-
Add 10 to both sides of the equation: \[ h = 50 + 10 \]
-
This simplifies to: \[ h = 60 \]
Therefore, Kelly's height is 60.
