That depends on the sizes of the other 2 angles if it's a right angle triangle then the other acute angle would be 70 degrees.
It is 90-28 = 62 degrees
Acute triangle Equal triangle
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
Yes because the measure of each angle in an equilateral triangle is 60 degrees which is an acute angle.
It is an acute angle if it measures 65 degrees
70
Each interior angle of an equilateral triangle measures 60 degrees
It is 90-28 = 62 degrees
The other acute angle in that triangle is 40 degrees.
72
67.5 ?
180 degrees in a triangle 180 - 90 - 55 = 35 35 degrees
A triangle which measures less than 90%
acute-angled triangle
Acute triangle Equal triangle
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.)
