12 × sin 45° = ...![]()
12 × sin 45° = ...
Penyelesaian
12 × sin 45°
= 12 × ½√2
= 12 × √2/2
= 12√2/2
[tex] \rm12 \times \sin( {45}^{ \circ} ) [/tex]
[tex] \rm = 12 \times \dfrac{1}{2} \sqrt{2} [/tex]
[tex] \rm = 12 \times \dfrac{ \sqrt{2} }{2}[/tex]
[tex] \rm = \dfrac{ 12\sqrt{2} }{2}[/tex]
[tex] \rm = \dfrac{ \cancel{12} \tiny{6} \: \sqrt{2} }{ \cancel2}[/tex]
[tex] \rm = 6 \sqrt{2} [/tex]
