Sketch of triangle:

Given a right triangle with angles $A$ and $B$ as the non-right angles. Determine if the statements are true or false. Justify your reasoning and show your argument.

9.

$\cos (A) = \frac{1}{\sin A}$

10.

$\tan (B) = \tan (90 - A)$

11.

$\tan (A) \cdot \cos (A) = \sin (A)$

Use a trigonometric equation to find the unknown side. Round values to the nearest tenth.
