The answer is acute, because acute angles are angles with a measurement of less than 90°. All the measurements they gave you were less than 90° Acute= less than 90° Obtuse=more than 90° Right=exactly 90° Hope this helps!!:)
This triangle is acute. Remember, triangles with 3 angles less that 90 are acute, triangles that hae an angle greater than 90 are obtuse, and triangles that have one 90 degree angle are right triangles. Hope this helps!!!
