Complementary angles have a sum of 90 degrees.
From the figure, the complementary angle of angle VST is angle USV.
And the measurement of this angle is :
[tex]\begin{gathered} \angle\text{USV}+\angle\text{VST}=90 \\ \angle\text{USV}+76=90 \\ \angle\text{USV}=14 \end{gathered}[/tex]
The answer is 14 degrees
