To find the measure of angle \( m\angle V \), we need to use properties of tangents to circles.

If \( UV \) is tangent to circle \( T \) at point \( V \), the angle formed between the tangent line \( UV \) and the radius \( TV \) is \( 90^\circ \). If we are given that \( m\angle UVT = 69^\circ \), we can find \( m\angle V \).

Since:

\[
m\angle UVT + m\angle V = 90^\circ
\]

We can substitute in what we know:

\[
69^\circ + m\angle V = 90^\circ
\]

Now we can solve for \( m\angle V \):

\[
m\angle V = 90^\circ - 69^\circ = 21^\circ
\]

So, the measure of angle \( V \) is:

\[
m\angle V = 21^\circ
\]
