There could be almost any acute angle. it maters what kind it is
Your question contains the answer. It is a 'right' triangle.
An 85 degree angle is acute. 1-89 = acute 90= right 91-180 = obtuse
With any type of triangle, the angles add up to 180 degrees. It does not matter if it is equilateral, scalene, or acute, or even right, obtuse, or acute.
Right angle. An acute angle is less than 90°. An obtuse angle is more than 90°. If it isn't less than or greater than, it must be equal to. Of course a straight angle is more or less an extreme case of an obtuse angle.
If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.
A right-angled triangle.
A right angle has a 90-degree and in two acute angles.
An obtuse triangle
60 degrees: acute
A right triangle is a triangle with a right angle.a right triangle is a triangle with 1 side as a right angle
An obtuse angle
A right triangle has a right angle (thus called a right triangle), 90 degrees
