Hint: Here convert the given radians into degrees, and this can be converted using the conversion formula i.e., degrees, and substituting the number of radians i.e., in this formula we will get the required converted degrees.
Complete step by step answer:
Degrees and radians are ways of measuring angles. A radian is equal to the amount an angle would have to be open to capture an arc of the circle's circumference of equal length to the circle's radius. (360 degrees) is equal to radians.
Given radian is rad,
We have to convert the radian into the degrees, by using the conversion formula.
We know that radians, then we can write 1 radian as, ,
Now using the formula we can convert radians into degree, here ,
By substituting the value of in the formula, we get,
degree,
By eliminating the like terms we get,
degrees,
Now simplifying we get,
degrees,
Again multiplying we get,
degrees,
The converted degree is 135 degrees.
The degree form when we convert radians to degrees is equal to 135 degrees.
Note: Do not mistake with the formula for conversion of angle to radians as, degrees, as it is a wrong formula, Only if then we can write it as, degrees.
Degrees are more common in general: there are 360 degrees in a whole circle, 180 degrees in a half circle, and 90 degrees in a quarter of a circle. A radian is the amount an angle has to open such that the length of the section of the circle's circumference it captures is equal to the length of the radius.
