Answer 2

Step-by-step explanation:

$sec45 + cos45$

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

Taking LCM

$= \frac{ \sqrt{2 \times \sqrt{2} } + 1 }{ \sqrt{2} }$

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

$= \frac{3}{ \sqrt{2} }$

Rationalising the denominator we get

$= \frac{3}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} }$

$= \frac{3 \sqrt{2} }{2}$
