1.	Use trigonometrical tables to find tangent of:(i) 37° (ii) 42° 18' (iii) 17° 27'
Answer» (i) tan 37° = 0.7536 (ii) tan 42° 18' = 0.9099 (iii) tan 17° 27' = tan (17° 24' + 3') = 0.3134 + 0.0010 = 0.3144

Use trigonometrical tables to find tangent of:(i) 37° (ii) 42° 18' (iii) 17° 27'

Answer»

(i) tan 37° = 0.7536

(ii) tan 42° 18' = 0.9099

(iii) tan 17° 27' = tan (17° 24' + 3') = 0.3134 + 0.0010 = 0.3144
