 Hi and welcome to the session. Let us discuss the following question which says find the degree measure corresponding to the following radian measure and the second part has minus four radians. So let us begin with the solution and we have to find the degree measure of minus four radian. Now since pi radian is equal to 180 degrees therefore one radian is equal to 180 degree upon pi and so minus four radian will be equal to minus four into 180 degree upon pi and since pi is equal to 22 upon 7 so we have minus four into 180 degree upon 22 into 7 which is further equal to minus 2520 upon 11 degrees and now let us divide 2520 by 11, 11 into 2 is 22, 3 remainder, now 2 carry down, 11 again into 2 is 22, 10 is remainder and we have 0, 11 into 9 is 99, 1 remainder. Now this is 1 degrees and 1 degree is equal to 1 into 60 minutes which is equal to 6 minutes and now let us divide 60 minutes by 11, 11 into 5 is 55, 5 remainder, 5 was in minutes and 5 into 60 equal to and on dividing 300 by 11 we have 11, 2 is 22, 8 carry down then we have 11, 7 is 77, 3 down then we have 11, 2 is 22, then we have 8 and then 0, 11 is 77, we have 3, again 30 and 11, 2 is 22, we have 8 and so on as we can say that minus 4 radian is equal to minus 229 degrees, 5 minutes and 27 seconds will be 27 seconds and that is our answer is minus 229 degrees, 5 minutes and 27 seconds. So this concludes the solution, hope you enjoyed it, take care and
