Answer 1

Answer:

1/1root2+1/2

=root2/1+1/2

=2root2+1/2

Answer 2

Hey Pretty Stranger!

$\sf \: \dfrac{ \sin {90}^{ \degree} }{ \cos {45}^{ \degree} } + \dfrac{1}{cosec \degree}$

Put the values :)

$\longrightarrow \sf \: \dfrac{1}{ \dfrac{1}{ \sqrt{2} } } + \dfrac{1}{2}$

$\longrightarrow \sf \: \sqrt{2} + \dfrac{1}{2}$

$\longrightarrow \sf \: \dfrac{2 \sqrt{2} + 1}{2}$
