Divide both sides by 4 to get

Recalling the definition of tangent as ratio between sine and cosine, we have

The sine and cosine of an angle are opposite only if the angle is

So, we have

So, the solutions are

Answer:
I ≈ 251188643
Step-by-step explanation:
Given
R = logI [ note log I =
I ]
Using the rule of logarithms
x = n ⇒ x = 
Substitute R = 8.4 into the equation, then
logI = 8.4
I =
≈ 251188643
