An exterior angle of an isosceles triangle has measure 150°. Find two possible sets of measures for the angles of the triangle.

If the exterior angle of the bases is 150°​, then the measure of the angle of each base is
_° and the measure of the vertex is
_°.
If the exterior angle of the vertex is 150°​, then the measure of the angle of each base is
_° and the measure of the vertex is
_°.

exterior + interior = 180

The interior angle could be either
the vertex angle
or one of the two base angles

Ext.Ang.Bases = 150
Int.Ang.Bases = 180-150 = 30 each
For whole triangle: 30+30+x = 180
Int.Ang.Vrtx. = x = 120

Ext.Ang.Vrtx. = 150
Int.Ang.Vrtx. = 180 - 150 = 30
Int.Ang.Bases = 180 - 30 = 150
Base angles are 0.5×150 = 75 each
