and so on
Answer:
Step-by-step explanation:
Several trig identities are involved in the proof of this. This is the order in which they are used.
- cos(2x) = cos²(x) -sin²(x)
- cos²(x) +sin²(x) = 1
- cos(x) = 1/sec(x)
<h3>Proof</h3>
Starting with the left side, we can transform it into the right side.

27/36 = n/4
27*4 = 36n
108 = 36n
108/36 = 36n/36
n = 3
The equation is 200+ 5s=x
