Answer:
17.25
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
secx =
, cosecx = 
cotx =
, tanx = 
Consider the left side
secA cosecA - cotA
=
×
- 
=
- 
= 
=
( cancel sinA on numerator/ denominator )
= 
= tanA = right side ⇒ proven
Cent is by the hundred so one percent is 1/100 so .6%=6/1000
which can be reduced to 3/500
