elena55 [62]

Answer:

Therefore 20 degree is in First Quadrant,

i.e Quadrant I.

Step-by-step explanation:

QUADRANT:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

Quadrant I      -          0° to 90°

Quadrant II     -       90° to 180°

Quadrant III    -      180° to 270°

Quadrant IV    -      270° to 360°

Therefore 20 degree is in First Quadrant, i.e Quadrant I.

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV  -          0° to -90°

Quadrant III   -       -90° to -180°

Quadrant II    -      -180° to -270°

Quadrant I     -      -270° to -360°
