No. The angles of a triangle always add up to exactly 180 degrees. A right triangle must have
one right angle, i.e. an angle of 90 degrees. That leaves 90 degrees for the other two angles.
38 and 54 add up to 92 degrees, so they can't co-exist with the 90-degree angle in a right triangle.

Two. Two acute angles in a right triangle.
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD
