Step-by-step explanation:
sin 46°= a/12.8
a = sin46° * 12.8 = 9.20
cos59°=b/16.8
b = cos59°*16.8 = 8.65

Answer:
The given equation having only one solution i.e., "w = 3". A further explanation is provided below.
Step-by-step explanation:
The given equation is:
⇒ ![9(w-9)-2=-7w+7(w-8)](https://tex.z-dn.net/?f=9%28w-9%29-2%3D-7w%2B7%28w-8%29)
By opening the brackets, we get
⇒ ![9w-81-2=-7w+7w-56](https://tex.z-dn.net/?f=9w-81-2%3D-7w%2B7w-56)
⇒ ![9w-83=-56](https://tex.z-dn.net/?f=9w-83%3D-56)
On adding "83" both sides, we get
⇒ ![9w-83+83=-56+83](https://tex.z-dn.net/?f=9w-83%2B83%3D-56%2B83)
⇒ ![9w=27](https://tex.z-dn.net/?f=9w%3D27)
⇒ ![w=\frac{27}{9}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B27%7D%7B9%7D)
⇒ ![=3](https://tex.z-dn.net/?f=%3D3)
