Answer:

57° 17'44" approximately

Table 1.2

sin ( - a) =

— sin a

tan ( - a) =

-tan a

sec ( - a)

=

sec a

cos ( - a) =

cos a

cot ( - a) =

-cot a

cosec ( - a)

=

- cosec a

sin (90°-a) =

cos a

tan (90°-a) =

cot a

sec (90° - a)

=

cosec a

cos (90°-a) =

sin a

cot (90°-a) =

tan a

cosec (90° - a)

=

sec a

sin (90° +a) =

cos a

tan (90° +a) =

-cot a

sec (90° +a)

=

— cosec a

cos (90° +a) =

-sin a

cot (90° +a) =

-tan a

cosec (90° + a)

=

sec a

sin (180°-a) =

sin a

tan (180°-a) =

-tan a

sec (180°-a)

=

- sec a

cos (180°-a) =

— cos a

cot (180° - a) =

— cot a

cosec (180°-a)

=

cosec a

sin (180° +a) =

- sin a

tan (180° + a) =

tan a

sec (180° +a)

=

-sec a

cos (180° + a) =

-cos a

cot (180° + a) =

cot a

cosec (180° +a)

=
