Okay so we have 15 hours already, now we need to add 60 minutes, which is exactly an hour.

So, 15 Hours + 1 Hour = 16 Hours.

16 Hours is your answer, I hope I helped and good luck studying!

Thank you,
Darian D.

Answer:

Verified

Step-by-step explanation:

Use $\tan{x}=\frac{\sin{x}}{\cos{x}}$ , $\sin^2{x}+\cos^2{x}=1$ and $\sec{x}=\frac{1}{\cos{x}}$

LHS= $\tan^2{x}+1=\frac{\sin^2{x}}{\cos^2{x}} + 1=\frac{\sin^2{x}+\cos^2{x}}{\cos^2{x}}=\frac{1}{\cos^2{x}}=\sec^2{x}$ =RHS
