Mathematics

Answer:

y = \frac{\pi}{3}

Step-by-step explanation:

using the addition formula for sine

sin(x + y) = sinxcosy + cosxsiny

then

sinxcosy + cosxsiny = \frac{1}{2} sinx + \frac{\sqrt{3} }{2} cosx

for the 2 sides to be equal , then

cosy = \frac{1}{2} and siny = \frac{\sqrt{3} }{2}

then

y = cos^{-1} (\frac{1}{2} ) = \frac{\pi }{3}

and

y = sin^{-1} ( \frac{\sqrt{3} }{2} ) = \frac{\pi }{3}

thus y = \frac{\pi }{3}
