The sum of angle 3x and 45 is equal to 72. So equation for x is,


3x+45=72

Simplify the equation to obtain the value of x.


\begin{gathered} 3x+45=72 \\ 3x=72-45 \\ 3x=27 \\ x=9 \end{gathered}

Determine the measure of angle 3x.


\begin{gathered} 3x=3\cdot9 \\ =27 \end{gathered}

So value of x is 9 and measure of angle 3x is 27 degree.
