Although the square root of 2 times the square root of 14 does equal the square root of 28, it is not simplified to the fullest extent. To simplify separate the square root of 28 into two factors, but make sure one is a perfect square. We can separate into 4 and 7, and since the square root of 4 is 2, we are left with 2* the square root of 7

Convert the degree measurement to radians. Express answer as multiple of
bixtya [17]

Given:

The given degree measurement is -60 degrees.

To find:

The radian measure of the given degree measure.

Solution:

We know that,

\text{Radian measure}=\text{Degree measure}\times \dfrac{\pi}{180^\circ}

The radian measure of -60 degrees.

\text{Radian measure}=-60^\circ \times \dfrac{\pi}{180^\circ}

\text{Radian measure}=-\dfrac{\pi}{3}

Therefore, the radian measure of the given degree measure is -\dfrac{\pi}{3}.
