Hey there!
We have to multiply, the "a" becomes a "negative a" ; solve this fraction to understand this step
Like: (multiplication) -a = 1/8
Let's multiply by a negative one on each of your sides
a = -(1/8)
* 1. * 1
Solve this and that gives us our answer⬆️
We have "two solutions " in this problem, which 1/8 or -1/8
Answer: 1/8 or -1/8 (option A)
Good luck on your assignment and enjoy your day

Explanation: If you plug in 120 for N you get -10(120)=-1200
Which is true.
Cos 60 = 1/2 --> Sin60 = sr(3)/2 = 0.866
Tan60 = 1/sr(3) = 0.577
