To find the third angle measure, we can use the fact that the sum of the angles in a triangle is always 180°.
22° + 46° + x = 180°
68° + x = 180°
x = 112°
So, the third angle measure is 112°.
Regarding the type of triangle, an obtuse triangle has one angle that is greater than 90°. Since the third angle measure is 112°, which is greater than 90°, the triangle is an obtuse triangle.
Therefore, the correct option is:
1. The third angle measure is 112°, and the triangle is an obtuse triangle.
