If the base angle of an isosceles triangle measures 15°, what is the measure of the other base angle?

The measure of the other base angle is:

Step-by-step explanation:

Isosceles triangles are characterized by having two equal internal angles, which are usually located at the base of the triangle, due to this, if one base angle measures 15°, surely the other base angle will measure the same and, since the sum of the interior angles of a triangle is 180°, the third angle must measure 150°.

i think the answer is b)

step-by-step explanation:

no this is a nonlinear negative
