answer...how to solve...

Answer 1

Hi Mate!!

1) Sec ( x ) = 1 / Cos ( x ) and. Tan ( x ) = Sin ( x ) / Cos ( x )

=>. √3 Cos ( x ) - Sin ( x ) = 1

Multiple both sides by 1 / 2

=>. { √ 3 / 2 } Cos ( x ) -{ 1 / 2 } Sin ( x ) = 1 / 2

=>. Sin ( 60 ) Cos ( x ) - Sin ( x ) Cos ( 60 ) = 1 / 2

=>. Sin ( 60 - x ) = Sin ( 30 )

=>. x = 30

2).

Sin ( 45 + x ) = 1

=>. Sin ( 45 + x ) = Sin ( 90 )

=>. x = 45

Have a nice time
