To determine what can be established in a triangle with a 22° angle and a 46° angle, we need to consider the properties of triangles.
In any triangle, the sum of the interior angles is always 180°. Therefore, we can find the measure of the third angle by subtracting the sum of the two given angles from 180°.
Third angle = 180° - (22° + 46°) = 112°
So, the third angle in this triangle is 112°.
Now, let's analyze the possible cases based on the measures of the angles:
1. If the third angle is greater than 90°:
In this case, the triangle is an obtuse triangle, because it has one angle greater than 90°. So, with a 22° angle, a 46° angle, and a third angle of 112°, we can establish that the triangle is an obtuse triangle.
2. If the third angle is equal to 90°:
In this case, the triangle is a right triangle, because it has one right angle (90°). However, since the third angle is 112°, which is greater than 90°, this combination of angles cannot form a right triangle.
3. If the third angle is less than 90°:
In this case, the triangle is an acute triangle, because all three angles are less than 90°. So, with a 22° angle, a 46° angle, and a third angle of 112°, we can establish that the triangle is an acute triangle.
Therefore, based on the measures of the given angles, we can establish that the triangle is either an obtuse triangle or an acute triangle.
