Question

If a triangle has a 22°
angle and a 46°
angle, what can be established about the third angle measure and the type of triangle?(1 point)

The third angle measure is 112°
, and the triangle is an acute triangle.

The third angle measure is 128°
, and the triangle is an obtuse triangle.

The third angle measure is 68°
, and the triangle is an obtuse triangle.

The third angle measure is  112°
, and the triangle is an obtuse triangle.

Answer 1

Sum of angles = 180°. Third angle = 180° − (22° + 46°) = 180° − 68° = 112°.
Since 112° > 90°, the triangle is obtuse.

Answer: The third angle is 112°, and the triangle is an obtuse triangle.
