Isoceles triangles have two equal sides and two equal angles. So if one base angle is 15°, the other base angle is 15°.

Hope this helps! :)

Answer:

The measure of the other base angle is:

  • 15°

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°.
