The measures of two angles of a triangle are 23 degrees, and 67 degrees. is the triangle acute, right, or obtuse?

Trick question - it’s a right triangle. Here’s why:

23 + 67 = 90. All triangles have an interior angle sum of 180. 180 - 90 = 90. 90 degrees is right, and therefore, having a right angle, this is a right triangle.
