Question

(in) sin 42° sec 48° + cos 42° cosec 48° = 2​

Answer 1

Answer:

2

Step-by-step explanation:

sin42 x 1/cos48 + cos 42 x 1/sin48

sin 42 x 1/sin42 + cos 42 x 1/cos 42

1+1

= 2

Answer 2

Answer:

2

Step-by-step explanation:

s

$\sin42 \times 1 \div \cos(48 ) + \cos(42) \times 1 \div \sin(48) \\ = \sin(90 - 48) \div \cos(48) + \cos(90 - 48) \div \sin(48 \\ = \cos(48) \div \cos(48 ) + \sin(48) \div \sin(48 ) \\ = 1 + 1 \\ = 2$
