Question:

If sin230° + cos230° + cot245° + tan260° - x = 6 , find the value of (x - 2).

Options:

2

-1

0

1

Correct Answer:

-1

Explanation:

⇒ sin230° + cos230° + cot245° + tan260° - x = 6

⇒ (\(\frac{1}{2}\))2 + (\(\frac{√3}{2}\))2 + 1 + (\(\sqrt {3}\))2 - x = 6

⇒ \(\frac{1}{4}\) + \(\frac{3}{4}\) + 1 + 3 - x = 6

⇒ 1 + 1 + 3 - x = 6

`x = 1

⇒ ( x - 2 ) = ( 1 - 2 ) = -1
