If tan230° + cot260° + sec260° + x = 5 , find the value of x . |
1 -\(\frac{1}{3}\) \(\frac{1}{3}\) \(\frac{2}{3}\) |
\(\frac{1}{3}\) |
⇒ tan230° + cot260° + sec260° + x = 5 ⇒ (\(\frac{1}{\sqrt {3}}\))2 + (\(\frac{1}{\sqrt {3}}\))2 + (2)2 + x = 5 ⇒ \(\frac{2}{3}\)+ 4 + x = 5 ⇒ x = 1 - \(\frac{2}{3}\) = \(\frac{1}{3}\) |
