90 degrees
A pair of supplementary angles adds up to 180 degrees. Therefore, the supplement to a 150 degree angle is 180 - 150 = 30 degrees.
Obtuse.
Yes, it is.

Interior angle is 150 degrees.
It is an angle measuring 30 degrees. But such an angle does not have a specific name.
An obtuse angle.
To construct an angle of 150 degrees using a compass, you would first draw a ray as the initial side of the angle. Then, place the compass on the vertex of the angle and draw an arc that intersects the initial ray at a point. Next, without changing the compass width, place the compass on the intersection point and draw another arc that intersects the previous arc. Finally, draw a ray from the vertex through the point of intersection of the two arcs to create an angle of 150 degrees.
