<gadget id="calculator">360/90</gadget>
<output>4</output>
4 111.10 degreePM   Now 18 hours have 360 degree   then 1 hour has  360/18= 
<gadget id="calculator"> 360/18</gadget>
<output>20</output>
20 degree   so 15 * 20 make 300 degree   hour hand= 300 + 50 * 2/9 =311.10 degree   minute hand = 50 * 4= 
<gadget id="calculator">50 * 4</gadget>
<output>200</output>
200 degree   here is the difference 311.10-200= 
<gadget id="calculator">311.10-200</gadget>
<output>111.1</output>
111.10 degree   ANSWER:111.10 degree
