90 degrees

First drop of knowledge: the angles of a triangle must combine to equal 180 degrees. An obtuse angle is more than 90 degrees, a right angle is 90 degrees, and an acute angle is less than 90 degrees. Because an obtuse angle is present, it is already over 90 degrees. Let's say it is the least possible whole number for an obtuse angle, which is 91 degrees. Two more obtuse angles would put it above 180 degrees, which is too much to be at triangle. Two right angles would still put it above 180 degrees, still too much. The only combination left is two acute angles (in this case, 45 and 44 degrees). Thus, even the lowest of whole numbers for an obtuse angle requires two acute angles, so any other higher number will require the same.

It is 2 and the 3rd angle must be an obtuse or a right angle because the 3 interior angles in a triangle add uo to 180 degrees.

if you are talking about regular polygons, then nothing has an obtuse angle. otherwise, pretty much any shape can have an obtuse angle

-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .

A hexagon has six angles. A regular hexagon has six angles and each one is equal in measure to 120 degrees. 120 degrees is an obtuse angle. Any regular polygon with at least 6 sides has at least 6 obtuse angles.

-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .

-- The sum of all three angles inside every triangle is always 180 degrees. -- An obtuse angle is an angle with more than 90 degrees in it. -- So two obtuse angles have more than 180 degrees between them. -- So they can't both be in the same triangle, unless at least part of one of them is left hanging out.

Yes, because the angles have to add up to 360º, at least one angle has to be obtuse.
