You can put this solution on YOUR website!
1)
Use +180%2Fpi+=+1+ degrees/radian as a multiplier
+%28+3%2F2%29%2Api%2A%28+180%2Fpi+%29+
+3%2A90+=+270 degrees
----------------------
2)
+pi%2F48+ radians
+%28+pi%2F48+%29%2A%28+180%2Fpi+%29+
+3.75+ degrees
and
+.75%2A%28+60%2F1+%29+ minutes/degree
+45+ minutes
adding:
+3+ degrees +45+ min
-------------------------
3)
+2%2A%285%2F6%29+ radians
+2%2A%285%2F6%29%2A%28+180%2Fpi+%29+
+2%2A%285%2F6%29%2A%28+180%2F3.14159+%29+ degrees
you can finish
----------------
4)
+1.236+ radians
+1.236%2A%28+180%2Fpi+%29+
+1.236%2A%28+180%2F3.14159+%29+
+222.48+%2F+3.14159+
+70.81758+
and
use
+60%2F1+ minutes/degree
+.81758%2A%28+60%2F1+%29+
+49.0548+ minutes
and
+.0548%2A%28+60%2F1+%29+seconds%2Fminute%0D%0A%7B%7B%7B+3.288+ seconds
adding:
70 degrees 49 minutes 3 seconds
