Rewrite the angle π/4 radians in degree measure.

• 90°

• 60°

• 45°

• 30°

• 120°

If cos θ < 0 and sin θ < 0, determine the quadrant in which the terminal side of θ lies.

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

• Quadrant II or III

Evaluate the sine of the angle without using a calculator. 120°

• 0
