Soln:Here, 85’’ = $\left( {\frac{{85}}{{100}}} \right) = \left( {\frac{{17}}{{20}}} \right)$, 2’ 85’’= $\left( {2 + \frac{{17}}{{20}}} \right) = {\frac{{57}}{{20}}^{\rm{'}}}$, ${\frac{{57}}{4}^{\rm{'}}}$ = ${\left( {\frac{{57}}{{20}}* \frac{1}{{100}}} \right)^{\rm{g}}} = {\left( {\frac{{57}}{{2000}}} \right)^{\rm{g}}} = {0.0285^{\rm{g}}}$, So, 80g 2’ 85’’ = (80 + 0.0285)g = 80. How To Respond To Sorry My Phone Died, Soln: Here, 27° = 27 $*$ 60’ = 1620’, So, 27°38’42’’ = (99480 + 42)° = 99522° ans, So, 10°25’48’’ = (37500 + 48)° = 37548° ans, So, 25°15’10’’ = (90900 + 10)° = 90910° ans, So, 45°10’’ = (162000 + 10)° = 162010° ans, f. Soln: Here, 150° = 150 $*$ 60’ = 9000’, So, 150°40’’ = (540000 + 40)° = 540040° ans, g. Soln: Here, 75g = 75 $*$ 100’ = 7500’, So, 75g 75’90’’ = (757500 + 90)° = 757590° ans, h. Soln: Here, 80g = 80 $*$ 100’ = 8000’, So, 80g78’’ = (800000 + 78)° = 800078° ans, 4.a. 3. 2627 $*$ 60 = 15.
