Given,
The measure of first angle of the triangle is 47 degree.
The measure of second angle of the triangle is 75 degree.
Consider, the measure of third angle of the triangle is x degree.
The sum of all interior angles of the triangle is 180 degree.
[tex]\begin{gathered} 47^{\circ}+75^{\circ}+x^{\circ}=180^{\circ} \\ x^{\circ}=180^{\circ}-(122^{\circ}) \\ x^{\circ}=58^{\circ} \end{gathered}[/tex]Hence, the measure of the third angle is 58 degree.
