Two directions are recorded as 12mo17′30.5′′ and −5mo42′15.2′′.
(i) Express 12mo17′30.5′′ in decimal degrees, correct to 0.01o.
(ii) Express −5o42′15.2′′ in decimal degrees, correct to 0.01o.
(iii) Hence determine the total angular separation between the two directions in decimal degrees, correct to 0.01o.
