Answer:
It is an acute triangle.
Step-by-step explanation:
An acute triangle is a triangle in which all angles measure less than 90°. All three angles of this triangle are less than 90, so this is an acute triangle.
A right triangle is a triangle with one right angle (measures 90°); this does not have a right angle so this is not a right triangle.
An obtuse triangle is a triangle with one obtuse angle (more than 90°). This triangle does not have an obtuse angle so this is not an obtuse triangle.
An equiangular triangle is one where all three angles measure the same. These three angles are all different, so this is not equiangular.
