#### Answer

$$7$$

#### Work Step by Step

The distance $d$ between the two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is given by
$$d=\sqrt {(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}.$$
Substitute $x_{1}=3$, $y_{1}=-2$, $x_{2}=3$ and $y_{2}=5:$
$$d=\sqrt {(3-3)^{2}+(5-(-2))^{2}}=\sqrt {0+49}=\sqrt{49}=7.$$
