Answer:
The square root of this is 80047
Step-by-step explanation:

We know that : (a - b)(a + b) = a² - b²

We know that : 1 - sin²x = cos²x



We know that : sec²x = 1 + tan²x







It would be: 37 × 0.8108 = 30 hours (approx.)
Now, we know, 1 hour = 60 min.
so, 30 hours = 60 × 30 = 1800 min.
In short, Your Answer would be 1800 min
Hope this helps!
