I need help figuring out what I did wrong

rewona [7]

Answer:

Step-by-step explanation:

Using the addition formula for sine

sin(a + b) = sinacosb + cosasinb

and the exact values

sin( $\frac{\pi }{4}$ ) = cos( $\frac{\pi }{4}$ ) = $\frac{\sqrt{2} }{2}$ , cos( $\frac{\pi }{6}$ ) = $\frac{\sqrt{3} }{2}$ , sin( $\frac{\pi }{6}$ ) = $\frac{1}{2}$

Note that $\frac{5\pi }{12}$ = $\frac{\pi }{4}$ + $\frac{\pi }{6}$ , thus

sin( $\frac{5\pi }{12}$ )

= sin( $\frac{\pi }{4}$ + $\frac{\pi }{6}$ )

= sin( $\frac{\pi }{4}$ )cos( $\frac{\pi }{6}$ ) + cos( $\frac{\pi }{4}$ )sin( $\frac{\pi }{6}$ )

= ( $\frac{\sqrt{2} }{2}$ × $\frac{\sqrt{3} }{2}$ ) + ( $\frac{\sqrt{2} }{2}$ × $\frac{1}{2}$ )

= $\frac{\sqrt{6} }{4}$ + $\frac{\sqrt{2} }{4}$

= $\frac{\sqrt{6}+\sqrt{2} }{4}$ → D
