NO 1
sin 45° + cos 45°
[tex] = \frac{ \sqrt{2} }{2} + \frac{ \sqrt{2} }{2} \\ \\ = \frac{ \sqrt{2 +2} }{2} \\ \\ = \frac{2 \sqrt{2} }{2} \\ \\ = \sqrt{2} [/tex]
NO 2
sin 45° + sin 30°
= √2/2 + 1/2
= 1+√2/2

Nomor 1:
[tex] \sin( {45}^{ \circ} ) + \cos( {45}^{ \circ} )[/tex]
[tex] = \frac{ \sqrt{2} }{2} + \frac { \sqrt{2} }{2} [/tex]
[tex] = \frac{ \not2 \sqrt{2} }{ \not2} [/tex]
[tex] = \sqrt{2} [/tex]
..
Nomor 2:
[tex] \sin( {45}^{ \circ} ) + \sin( {30}^{ \circ} )[/tex]
[tex] = \frac{ \sqrt{2} }{2} + \frac{1}{2}[/tex]
[tex] = \frac{1 + \sqrt{2} }{2} [/tex]
