Question

if Sec 5 theta = Co Sec (theta+36degree) then
value of cosec 5theta=?​

Answer 1

Answer:

Step-by-step explanation:

We know,

Cosec(90 - ∅) = sec∅

---------------------------------------------

=>Sec5A = cosec(A - 36)

=> Cosec(90 - 5A) = cosec(A - 36)  

=>90 - 5A = A - 36

=>90 + 36 = A + 5A

=>126 = 6A

=>126/6 = A

=>21 = A

Cosec (5*21) = cosec(105) = √2(√3-1)

=>

Answer 2

Answer:

=>Sec5A = cosec(A - 36)

=> Cosec(90 - 5A) = cosec(A - 36)  

=>90 - 5A = A - 36

=>90 + 36 = A + 5A

=>126 = 6A

=>126/6 = A

=>21 = A

Cosec (5*21) = cosec(105) = √2(√3-1)
