Answer with explanation:

In the problem ,theta is replaced by A.

Use the following trigonometric identity to solve the problem

$1.sin^2A+cos^2A=1\\\\2.tan A=\frac{sinA}{cosA}$

The Given function is

$\frac{sin A}{\sqrt{1-sin^2A}}\\\\= \frac{sinA}{\sqrt{cos^2A}}\\\\=\frac{sinA}{cosA}\\\\=tan A$

19=h/3 -8 whats h??

creativ13 [48]

First add the 8 to both sides, canceling out the 8 in the right and adding it to the 19 on the left, making it 27. Multiplying undoes division so, After that, multiply by three on both sides, canceling out the three on the right and multiply 27 by 3, making it 81.
