20, 70 and 90 degrees.
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.
An acute angle measures less than 90 degrees. While a triangle may have 2 acute angles and 1 obtuse, this is not a requirement. A triangle may have three acute angles such and a 60-60-60 equilateral triangle.
A right angle triangle always has a 90 degree angle and two acute angles which altogether add up to 180 degrees.
A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
A triangle which measures less than 90%
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.)
The acute triangle will have 3 different acute angle that add up to 180 degrees
All triangles have 3 interior angles that add up to 180 degrees and they are:- Right angle triangle: 90 degree angle and 2 acute angles Obtuse triangle: An obtuse angle and 2 acute angles Scalene triangle: 3 acute angles of different sizes Isosceles triangle: 2 equal angles and another angle Equilateral triangle: 3 equal angles that each measures 60 degrees
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 will be a right angle triangle with a 90 degree angle and 2 acute angles
An acute angle measures less than 90 degrees. While a triangle may have 2 acute angles and 1 obtuse, this is not a requirement. A triangle may have three acute angles such and a 60-60-60 equilateral triangle.
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
The other acute angle in that triangle is 40 degrees.

'a' and 'b' must both be acute, complementary angles.
A right angle triangle always has a 90 degree angle and two acute angles which altogether add up to 180 degrees.
