what fraction of aright angle is 18
18º?
A right angle = 90º
18º/90º = ?
Does that help?
To calculate the fraction of a right angle that is 18, we need to determine the total number of degrees in a right angle.
A right angle measures 90 degrees. Therefore, the fraction of a right angle that is 18 degrees can be calculated as follows:
Fraction = Angle measurement / Total angle measurement
Fraction = 18° / 90°
Simplifying the fraction:
Fraction = 1 / 5
So, 18 degrees is one-fifth of a right angle.
To find the fraction of a right angle that 18 degrees represents, we need to compare it to the total number of degrees in a right angle, which is 90 degrees.
To calculate the fraction, divide the given angle measurement (18 degrees) by the total number of degrees in a right angle (90 degrees):
Fraction = 18 degrees / 90 degrees
Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 18 and 90 is 18.
18 degrees / 90 degrees = 1/5
So, 18 degrees is 1/5th (one-fifth) of a right angle.
