Web12 okt. 2024 · To classify an angle, first measure its size in degrees. Then compare this angle to the following values: If the angle is less than 90°, it is an acute angle. If the angle is exactly 90°, it is a right angle. If the angle is between 90° and 180°, it is an obtuse angle. If the angle is exactly 180°, it is a straight line. WebAn obtuse angle is an angle that measures greater than 90 degrees and less than 180 degrees. It is considered a type of acute angle. The degree of an obtuse angle is the …

How many degrees does an obtuse triangle...
WebThe measures of the three angles are x, y, and z. Because the sum of the measures of the angles in any triangle must be 180 degrees, we know that x + y + z = 180. We can use this equation, along with the other two equations given, to form this system of equations: x + y + z = 180 y = 2z z = 0.5x - 30
