19200 all you have to do to figure this out is multiply 100 times 8 since the is 8 halfs in 4 hours.

The answer would be: 5 + 9u
22' is 22 minutes
there are 60 minutes in 1 degree, how many in 22? well, the short answer is you divide it by 60, or 22/60 0.37 or thereabouts, so that makes it
121.037 degrees and 36''
36'' is 36 seconds, there are 60 seconds in 1 minute, so in short, just divide it by 60 as well, so 36/60 or 0.6 minutes
so, let us revise above some
121 degrees 22' and 36''
22' and 36'' is 22.6' because 36'' is 0.6'
how much is 22.6' in degrees? well 22.6/60
or about .38
so. 121° 22' 36'' will be 121.38° approximately
To do this, we must find the supplementary angle to those that are given.
The supplementary angle to 152 is 28, 54 is 126, 28 is 152, and 146 is 34
As 152 is 28, and 28 is 152, they are parallel,
So the answer would be lines e and g are parallel
