That would be the letter, "Ell". "L" "E", "F", "H", and "T" also have right angles in them, but "L" is the only letter with just one right angle in it.
Acute
We are not here to do your homework for you.
Only one.
The short answer is: because that is what a kite is. Long answer (although some minor steps have been skipped): Consider a kite, ABCD, where AB = DA and BC = CD Draw the diagonal AC. Then triangles ABC and ACD are congruent (SSS). So angle BAC = angle DAC. Now draw diagonal BD which intersects AC at E. Then triangles ABE and ADE are congruent (SAS) So angle AEB = angle AED. But these angles are supplementary. Therefore they must be right angles.
There are no right angles in the letter "e".
8
Right angles
Probably E - since it has four right-angles.
The capital letter E has no acute angles but it does have right angles.
Right angles of 90 degrees
Both do.
Right and straight

theres only one. A right angle
That would be the letter, "Ell". "L" "E", "F", "H", and "T" also have right angles in them, but "L" is the only letter with just one right angle in it.
it will be 6 or 7 or8 or9
