Two angles whos sum equals ninety degrees
If the given numbers represent degrees then it is a right angle triangle whos 3 angles add up to 180 degrees.
The three angles in a triangle add up to 180o so if you add the two you know, 34 and 105, you get 139o. Taking 139 from 180 gives 41, so the third angle is 41o.
they are vertical angles
An obtuse triangle is a triangle whos angle measure is greater than 180. The length of the sides of a scalene triangle are all different.
Two angles whos sum equals ninety degrees
45, 45 and 90 degrees

If the question refers to, What are Two angles that total 180° ? then :-These angles are supplementary angles.
I'm not sure I understand your actual question, but what you are actually asking with the wording is false. Two 30 degree angles would both be acute angles whos sum would only create another acute angle of 60 degrees. But if you have 2 acute angles, then the third would have to be obtuse to form a triangle.
An obtuse triangle is a triangle whos angle measure is greater than 180. The length of the sides of a scalene triangle are all different.
The sum of two complementary angles is 90 degrees.
The term supplementary angle is used to refer to angles whose sum is 180 degrees. This is different from complementary angles which add up to 90 degrees.
