Answer 1

Answer:

$\frac{ \tan 45\degree }{cosec \: 45\degree} - \frac{ 5\sin90\degree}{ 2\cos 0\degree} + \frac{ \sec 60\degree}{ \cot45 \degree } \\ \\ = \frac{1}{ \sqrt{2} } - \frac{5 \times 1}{2 \times 1} + \frac{2}{1} \\ \\ = \frac{2 - 5 \sqrt{2} + 2 \sqrt{2} }{2 \sqrt{2} } \\ \\ = \frac{2 - 3 \sqrt{2} }{ \sqrt{2} } \\ \\ = \frac{ \sqrt{2}( \sqrt{2} - 3) }{2 \sqrt{2} } \\ \\ = \frac{ \sqrt{2} - 3 }{2} \\ \\\red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
