128 Thoughts on Samsung Blinking Dash/Line Error Code List. Hi, we have another error on our fridge Samsung RSE8KPAS. and the self diag shows error not described in your list. There are [88 88] and your manual showing the description of 2nd and 4th EIGHTs, but our diag. shows the error of first EIGTH.
We use the outer scale to measure the angle PQR, as the arm PQ passes through the zero of the outer scale. Following the outer scale around the protractor, we find that the other arm, QR, passes through the outer scale at 120. So, the size of angle PQR is 120 degrees.
We can define 180 degrees as $\pi$ radians and 90 degrees as $\frac{\pi}{2}$ radians. The radian measure $\theta$ of the angle is the ratio of the arc length s to the radius r. Formula for radian measure of an angle is as follows: $\theta$ = $\frac{s}{r}$. where, s is the length of the arc intercepted by the circle. $\theta$ is measured in radians.
