Answer:
k = 8.4, j = 13.1
Step-by-step explanation:
Solve for k:
![tan(40)=\frac{k}{10}\\10(tan(40))=k\\8.4=k](https://tex.z-dn.net/?f=tan%2840%29%3D%5Cfrac%7Bk%7D%7B10%7D%5C%5C10%28tan%2840%29%29%3Dk%5C%5C8.4%3Dk)
Solve for j:
![8.4^2+10^2=j^2\\70.56+100=j^2\\170.56=j^2\\13.1=j](https://tex.z-dn.net/?f=8.4%5E2%2B10%5E2%3Dj%5E2%5C%5C70.56%2B100%3Dj%5E2%5C%5C170.56%3Dj%5E2%5C%5C13.1%3Dj)

Answer:
adult $13 student $15
Step-by-step explanation:
A=adult S = student
9A + 4S = 177
1A + 4S = 73
Multiply the second by (-1)
9A +4S = 177
-1A -4S = -73
ADD BOTH (4S will be cancelled)
8A = 104
A = 13 ( Adult ticket = $13)
13 + 4S = 73
4S = 60
S = 15 ( student ticket $15)
830,040 = 8 x 10^5 + 3 x 10^4 + 4 x 10
