P and Q be centers of two circle having radius 200cms. These circle intersect each other at some point A and B. Length of PQ is 250 cms. What will the angle AQP be? Pick one.
A) between 0 to 45	B) between 0 to 30	C) between 0 to 60	D) between 0 to 75	E) between 0 to 95
raw the diagram, in triangle AQP, AP = 200 , AQ = 200 and PQ = 250   cos(AQP)= (200^2+250^2-200^2)/(2*200*250)= 5/8= 
<gadget id="calculator">5/8</gadget>
<output>5/8 = around 0.625</output>
.625 [using cal, cos(AQP)= 51]   or,   as cos45=.7 &amp; cos60=.5 so, cos(AQP)=.625 lies betn angles 45 &amp; 60   between 0 to 60   ANSWER:between 0 to 60
<result>C</result>
