Please, Solve This Maths For Me (urgent)

Dear Friends,
Please, help solve this maths for me:


1. Show that  (1 + sin x)  (1 + secx)   = Tan x 
          ( 1 + because x)  (1 + cosecant x)

(please, note: it is numerators (1 + sin x)(1 + sec x) over denominators 1 + because x) (1 + cosecant x) = Tan x)

2. Express the following angles in degrees
   (i) 370  (ii) -430  10' (i.e. 10' is 10 seconds)

3. Express the following angle sin radiant
   (i) 21 radiant  (ii) п  radiant (i.e. pie over 12)
                12

Please, give details so I can learn.

Many thanks.

Kindy
