Because the angle measures greater than a square corner of 90$^{\circ}$ and less than a straight line of 180$^{\circ}$ it is a(n) Obtuse Angle.
To determine the type of angle simply measure the given angle with a protractor. An Obtuse Angle is an angle with a measurement greater than 90$^{\circ}$. Since the given angle measures greater than 90$^{\circ}$ it is an Obtuse Angle.
