The third angle measure is 180° - (22° + 46°) = 180° - 68° = 112°, and the triangle is an obtuse triangle.
Can a triangle have two right angles, and why or why not?(1 point)
Responses
Yes, because 90 + 90 = 180.
Yes, because 90 plus 90 equals 180 .
No, because a triangle must have an obtuse angle.
No, because a triangle must have an obtuse angle.
Yes, because it would be a right triangle.
Yes, because it would be a right triangle.
No, because there needs to be a third angle.

Yes, because it would be a right triangle.
No, because there needs to be a third angle.
No, because the sum of the interior angles of a triangle is always 180 degrees. If two angles are already 90 degrees each, the sum would be 90 + 90 = 180 degrees, leaving no room for a third angle.

Use the figure to answer the question.
An inclined transversal passes through two vertical parallel lines labeled upper M and upper N. The angles formed around the intersection point of upper M are labeled clockwise, starting from the upper left quadrant: 1, 2, 4, and 3. The corresponding angles formed around the intersection point of upper N are labeled clockwise, starting from the upper left quadrant: 5, 6, 8, and 7.
