Question

(1) if cosec A= sec 42° then find A.
(2) if tan B = cot 36° then find B.​

Answer 1

Answer:

1) A= 48

2) B= 54

Step-by-step explanation:

Using complementary functions :

cosec ( 90 - x ) = sec x

in the question x= 42 given

so 90- 42 = 48 (ans)

2) similarly

using function :

tan (90-x) = cot x

so x= 36

90-36 = 54 (ans)

THESE ARE THE FUNCTIONS TO BE USED .

hope it helps
