Answer 1

Answer:

see the above attachment for the answer

Answer 2

Explanation:

a = theta

sin (90 - a ) = cos a

Cos (90 - a ) = sin a

sec (90- a ) = cosec a

$cos a \div cosa \: + sin \: a \: \div cosec \: a \: - 3 {tan}^{2} 30$

so

1 + sin a / cosec a - 3(1/3) (sin a/ cosec a = sin square a )

$1 + {sin}^{2} a - 1$

ANSWER IS SIN SQUARE A
