The answer is
![x = 10 \sqrt{3} \\ y = 5 \sqrt{3}](https://tex.z-dn.net/?f=x%20%3D%2010%20%5Csqrt%7B3%7D%20%20%5C%5C%20y%20%3D%205%20%5Csqrt%7B3%7D%20)
Step-by-step explanation:
![\sin(60) = \frac{15}{x} \\ x= \frac{15}{ \sin(60) } = 10 \sqrt{3} \\ \sin(30) = \frac{y}{10 \sqrt{3} } \\ y = 10 \sqrt{3} \sin(30) \\ y = 10 \sqrt{3} \times .5 \\ y = 5 \sqrt{3}](https://tex.z-dn.net/?f=%20%5Csin%2860%29%20%20%3D%20%20%5Cfrac%7B15%7D%7Bx%7D%20%20%5C%5C%20x%3D%20%20%5Cfrac%7B15%7D%7B%20%5Csin%2860%29%20%7D%20%20%3D%2010%20%5Csqrt%7B3%7D%20%20%5C%5C%20%5Csin%2830%29%20%20%3D%20%20%5Cfrac%7By%7D%7B10%20%5Csqrt%7B3%7D%20%7D%20%20%5C%5C%20y%20%3D%2010%20%5Csqrt%7B3%7D%20%20%5Csin%2830%29%20%20%5C%5C%20y%20%3D%2010%20%5Csqrt%7B3%7D%20%20%5Ctimes%20.5%20%5C%5C%20y%20%3D%205%20%5Csqrt%7B3%7D%20)
