The question appears to relate to the angles of a triangle.
1) If angle 3 is acute then the other two angles can also be acute. In the case of an equilateral triangle all three angles are equal and acute.
2) If angle 3 is acute and one other angle is obtuse then the remaining angle is acute.
3) If angle 3 is acute and one other angle is a right angle then the remaining angle is acute.

What is the third angle of triangle if one is 27 the other 58?
when you add up all the angles of a triagle they equal 180 angle 1 + angle 2 + angle 3 = 180 27 + 58 + angle 3 = 180 85 + angle 3 = 180 angle 3 = 180 - 85 angle 3 = 95
How do you classify a triangle by the sizes of there angles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- Right angle triangle:a 90 degree angle and 2 acute angles Scalene triangle: 3 acute angles Obtuse triangle: an obtuse angle and 2 acute angles Isosceles triangle: 2 equal base angles and an apex angle Equilateral triangle: 3 equal angles each measuring 60 degrees
What triangle has 3 angles that are smaller than a right angle?
An equilateral triangle.
How many right angles can a quadrilateral have?
a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
What is the angle addition property?
If an angle has been bisected by a ray then it's now 3 angles ( the original 1, and the two created by the ray) this property says you can add the measurements of the two angles together to get the measurement of the original angle
