Usually none. But in some fonts, the intersection of the angled lines may be a right angle in either lowercase or uppercase.
K and R are two possibilities.
It could be on the right hand side of the letter k depending on how k is written
Three letters that have obtuse angles are "A," "K," and "R." In the letter "A," the angles formed at the top are obtuse. The letter "K" has an obtuse angle between the vertical line and the upper diagonal line, while "R" features an obtuse angle where the curved section meets the vertical line.
A hexagon can be broken into any number, k (≥3) of trapezoids, and these will have 4k angles.
None
The letter "K"
The answer depends on the font: it is 0 or 1.
4 angles
K and R are two possibilities.
Well, we have no idea what angle you're talking about.
None
There are no angles they are all obtuse angles
There are two acute in the letter k

The uppercase letters B, D, E, F, H, J, L, P, R, and T have right angles, and K does in some fonts, as well as the letter I when it has a top and bottom. The lowercase letters, unless deliberately curved are a, b, d, f, and t and sometimes k and p, and l (L) if it has a horizontal base. The letter e has an intersection where the right angle has no actual length due to its curve.
