If: 8x+12x = 90
Then: 20x = 90
And: x = 4.5
A right angled triangle can only have two acute angles.
The sum of two acute angles of a right triangle must equal 90 degrees.
A right triangle is a triangle with one of its angles being 90o. The requirements for the other two angles are that they both be acute and total to 90o. Therefore, the largest possible acute angle in a right triangle is 89.99999...o.
The three kinds of triangles are:right triangle :one of the angles is a right angle (i.e. measures 90 degrees)acute: All of the angles measures less than 90 degrees. A special case of acute isthe equiangular or equilateral triangle in which all angles measure 60 degrees;obtuse: One of the angles measure more than 90 degrees.
A right angle triangle has 2 acute angles that add up to 90 degrees, along with 1 right angle of 90 degrees.
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
An acute 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.
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.)
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
A right angled triangle can only have two acute angles.
Two. Two acute angles in a right triangle.
It is 90 degrees and the other 2 angles are acute
Could be a 90-60-30 degree triangle. so, 60 degrees.
False ------------------------------------ An acute triangle is one in which all angles are acute angles. An acute angle is less than 90°. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle.
The sum of the angles of a triangle is 180 degrees. A right angle is 90 degrees. So the sum of the remaining two acute angles of a right triangle is 90 degrees.
