If \( \sin \theta \) s -0.7660 , which of the following represents an approximate value of \( \tan \theta \), for \( 180^{\circ}<\theta<270^{\circ} \) ? 0.7660 0.8392 1.1916 1.4198

Convert the angle \( \theta=\frac{3 \pi}{5} \) radians to degrees. Express your answer exactly.

GEOMETRY. Use a calculator to find \( \tan 15^{\circ} \). Round to the nearest thousandth.

Simplify fally: \( \sin \left(90^{\circ}-x\right) \cdot \cos \left(180^{\circ}+x\right)+\tan x \cdot \cos x \cdot \sin \left(x-180^{\circ}\right) \) 5.2 Prove, WrTHOUT using a calculator, that \( \frac{\sin 315^{\circ} \cdot \tan 210^{\circ} \cdot \sin 190^{\circ}}{\cos 100^{\circ} \cdot \sin 120^{\circ}}=\frac{-\sqrt{2}}{3} \)

Use a calculator to find \( \tan 27^{\circ} \). Round to the nearest thousandth.

Convert the angle \( \theta=230^{\circ} \) to radians. Express your answer exactly. \( \theta=\square \) radians
