Hey there!
Use the pythagorean theorem:
a² + b² = c²
a will be rise and b will be run.
Distance between 9 and 2 is 7.
Distance between 3 and 0 is 3.
Plug those into the equation.
7² + 3² = c²
Square.
49 + 9 = c²
Add.
58 = c²
Square root both sides.
√58 = c
This is the distance in radical form.
Hope this helps!
