Step-by-step explanation:
![5x + 2y = 8](https://tex.z-dn.net/?f=5x%20%2B%202y%20%3D%208)
![2y = - 5x + 8](https://tex.z-dn.net/?f=2y%20%3D%20%20-%205x%20%2B%208)
![y = \frac{ - 5x}{2} + \frac{8}{2}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B%20-%205x%7D%7B2%7D%20%20%2B%20%20%5Cfrac%7B8%7D%7B2%7D%20)
![y = \frac{ - 5x}{2} + 4](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B%20-%205x%7D%7B2%7D%20%20%2B%204)

Step-by-step explanation:
sin(55) = x/21
x = 21sin(55)
use calculator in degree mode
cos(55) = y/21
21cos(55) = y
