All triangles have interior angles that add to 180 degrees. Let's call the 3 angles A,B, and C and angles A the 90 degree one. If 90+B+C=180. If angle B was the angle greater than 90 degrees (obtuse) then C would be 0 or negative degrees. Therefore, a right triangle can't have an obtuse interior angle.
Sum of all angles in a triangle is 180o. In a right triangle one angle is 90o and other two angles sum up to 90o.
A right triangle can't have an obtuse angle because obtuse angle is greater than 90o. So, sum of the two angles(right angle and obtuse angle) will be greater than 180o which is not possible.

What does the angles add upto in a right angle triangle?
The interior angles of a triangle add to 180 degrees. This is true for any triangle, whether it is obtuse angled, right angles or acute.
How many equal angles and right angles has a obtuse triangle have?
An obtuse triangle can have no right angles, and has two equal angles.
Number of obtuse angles in a right triangle?
There are no obtuse angles in a right triangle. A right triangle consists of one right angle and two acute angles.
How many obtuse angles does a right triangle contain?
No right triangle can have any obtuse angles inside it.
Can an obtuse triangle have two complementary interior angles?
No. A triangle with two complementary interior angles will always result into right triangle. The sum of the complementary angles will always be 90 degrees and the other one will be 90 too.
