Explain how you would plot (-5 3) on a coordinate plane

Start at the origin to plot the point. The x-coordinate, 3, indicates that you need to move 3 units to the right. The y-coordinate, −5, indicates that you need to move down 5 units. Then plot the point.

∠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°
