Answer 1

Answer:

sorry I don't know sorry

Answer 2

Answer:

Given that

\frac{(sin30 + tan45 - cosec60)}{(sec30 + cos60 + cot45)}

\frac{ \frac{1}{2}+1- \frac{2}{ \sqrt{3}} }{ \frac{2}{ \sqrt{3}}+ \frac{1}{2}+1}

\frac{ \sqrt{3}+2 \sqrt{3} - 4 }{4 + \sqrt{3} + 2 \sqrt{3} }

\frac{ 3 \sqrt{3} - 4 }{4 + 3 \sqrt{3} }

Rationalise the denominator

\frac{ 3 \sqrt{3} - 4 }{4 + 3 \sqrt{3} } * \frac{ 3 \sqrt{3} - 4 }{3 \sqrt{3} - 4 }

\frac{(3 \sqrt{3} - 4 )^2}{ (3 \sqrt{3} )^2-(4)^2 }

\frac{27+16-24 \sqrt{3} }{27-16}

\frac{43-24 \sqrt{3} }{11}
