Asap giving 30 points + brainliest + (on both the answer and profile) point q is plotted on the coordinate grid. point p is at (20, −30). point r is vertically above point q. it is at the same distance from point q as point p is from point q. which of these shows the coordinates of point r and its distance from point q?

Ok by the choices it should be the first choice(A.)

Point R is at (-40,30) 60 units away from point Q

Hope that I could help you.

∠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°
