Draw an angle with the given measure in standard position.
2. 60 degrees
3. -135 degrees
4. 450 degrees
5. -1125 degrees

 see graphs

Step-by-step explanation:

start at the origin and draw an arrow...

2) 60° counterclockwise = 60°

3) 135° clockwise (360 - 135) = 225°

4) one full ring counterclockwise plus (450 - 360) = 90°

5) three full rings clockwise plus (360(4) - 1125) = 315°

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
