Step-by-step explanation:

Sec 4 A = Cosec ( A - 20 )

sec (90-theta) = Cosec theta

Therefore Cosec (90-A) = Cosec (A-20)

90-A = A-20

90+20 = 2A

A = 110/2

Therefore A = 55°

Answer:

Cosec(90-A)=cosec(A-20)

Step-by-step explanation:

Cosec cosec will be canceled

So we will ger 90-A=A-20

90+20=2A

110=2A

A=55
