Question

if sec 2A=cosec(A-27) where 2A is then find the measure of a​

Answer 1

Answer:

cosec(90-2A )= Cosec (A-27)

90-2A=A-27

90+27=A+2A

117=3A

117/3=A

39=A

Answer 2

Answer:

the measure of A is 39°

Step-by-step explanation:

sec 2A = cosec(A-27°)

cosec (90°-2A) = cosec(A-27°)

90°-2A =A-27

90°+27° = A+2A

117° =3A

117°÷3 =A

A =39°
