cos0 degree+sin90 degree+root 2 sin45 degree

Answer 1

$\LARGE\star\mathfrak{\underline{\underline{\red{answer: }}}}$

$cos \: 0 \degree + sin \: 90 \degree + \sqrt{2} sin \: 45 \degree \\ \\ = (1) + (1) + \sqrt{2} ( \frac{1}{ \sqrt{2} } ) \\ \\ = 1 + 1 + \cancel{\sqrt{2} } \times \frac{1}{ \cancel{ \sqrt{2}} } \\ \\ = 1 + 1 + 1 \\ \\ = \underline{ \: \: 3 \: \: }$
