log(sinx)=-.49928 find x? the answer is 18 degree 28 minutes what should i do to get the answer in this format? also if I get inverse sine then inverse log I wont get the right answer?
log10( sin(x) ) = -0.49928
Write into exponential form: sin(x) = 10-0.49928
---> sin(x) = 0.3167524626
Find sin-1(x) ---> x = sin-1( 0.3167524626 )
---> x = 18.46664082
Converting the decimal 0.46664082 into minutes ---> 0.46664082 x 60 = 27.9984492 ---> 28
So: x = 18° 28'
