if the angle at a equals X then the angle at b equals X+40 and the angle at c equals X+20 the sum of the angels in a triangle is 360 degrees so: X + X+40 + X+20 = 360 3X + 60 = 360 3X = 300 X = 100.
An angle less than 90 degrees is called an acute angle.
An angle that is less than 900 is called an acute angle.
An angle greater than 0 but less than 90 degrees is an acute angle An angle of 90 degrees is a right angle An angle greater than 90 but less than 180 degrees is an obtuse angle An angle greater than 180 degrees is a reflex angle
Acute angle: greater than 0 but less than 90 degrees Right angle: exactly 90 degrees Obtuse angle: greater than 90 but less than 180 degrees Reflex angle: greater than 180 but less than 360 degrees
121 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees
if the angle at a equals X then the angle at b equals X+40 and the angle at c equals X+20 the sum of the angels in a triangle is 360 degrees so: X + X+40 + X+20 = 360 3X + 60 = 360 3X = 300 X = 100.
An angle greater than 0 but less than 90 degrees is an acute angle
A angle less than 90 degrees is a acute angle.
An angle less than 90 degrees is called an acute angle.
An Acute Angle is the kind of angle that is less than 90 degrees.
Acute angle: greater than 0 but less than 90 degrees Right angle: 90 degrees Obtuse angle: greater than 90 but less than 180 degrees Reflex angle: greater than 180 but less than 360 degrees
A reflex angle is an angle greater than 180 degrees but less than 360 degrees. Since 148 degrees is less than 180 degrees, it is not a reflex angle.
An angle greater than 0 but less than 90 degrees is an acute angle.
An angle greater than 0 but less than 90 degrees is an acute angle.
An angle that is less than 900 is called an acute angle.
An obtuse angle is greater than 90 degrees but less than 180 degrees
