Question

$\frac{ {tan}^{2} 45 - sin30}{1 + cos60 + {sin}^{2} 45}$
Find the solution !!!​

Answer 1

$= \frac{tan {}^{2} 45 - sin30}{1 + cos60 + sin {}^{2}45 }$

$= \frac{(1) {}^{2} - \frac{1}{2} }{1 + \frac{1}{2} + ( \frac{1}{ \sqrt{2} }) {}^{2} }$

$= \frac{ \frac{1}{2} }{ \frac{3}{2} + \frac{1}{2} }$

$= \frac{ \frac{1}{2} }{ 2 }$

$= \frac{1}{4}$
