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.
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
180 degrees in a triangle 180 - 90 - 55 = 35 35 degrees

67.5 ?
An acute triangle.
Could be a 90-60-30 degree triangle. so, 60 degrees.
50 degrees
Yes because the measure of each angle in an equilateral triangle is 60 degrees which is an acute angle.
The two acute angles total 90 degrees. If the larger angle is 4 times the smaller angle, then the smaller angle is 18 degrees and the larger angle is 72 degrees (4 x 18 degrees).
60.255 degrees (rounded)
The measure of the smaller acute angle of the triangle is: 17.46 degrees.
70
It is: 72 degrees
If its a right angle triangle then the second acute angle is 62 degrees
