Answer» <html><body><p>You're given air-to-glass is 3/2 which can be written: aRg = 3/2; similarly <a href="https://interviewquestions.tuteehub.com/tag/arw-2444217" style="font-weight:bold;" target="_blank" title="Click to know more about ARW">ARW</a> = 4/3 which <a href="https://interviewquestions.tuteehub.com/tag/also-373387" style="font-weight:bold;" target="_blank" title="Click to know more about ALSO">ALSO</a> means wRa=3/4 wRg (the target) = wRa x aRg = 3/4 x 3/2 = 9/8 We know SinC = 1/R so <a href="https://interviewquestions.tuteehub.com/tag/c-7168" style="font-weight:bold;" target="_blank" title="Click to know more about C">C</a> = <a href="https://interviewquestions.tuteehub.com/tag/arcsin-2441076" style="font-weight:bold;" target="_blank" title="Click to know more about ARCSIN">ARCSIN</a>(1/R) = ArcSin(8/9)(LIKE ME NOW)Explanation:</p></body></html> | |
