i calculated this problem and it's just 46.656
Answer:
46°
Step-by-step explanation:
When secants intersect each other and a circle, the external angle (A) is half the difference of the intercepted arcs:
∠A = (arcDC -arcBC)/2
12° = (arcDC -22°)/2 . . . . . . . fill in the given numbers
24° = arcDC -22° . . . . . . . . . multiply by 2
46° = arcDC . . . . . . . . . . . . . add 22°
K=8k+28
subtract 8k from both side
-7k = 28
divide both side by -7
k= -4
(-3,7)(9,5)
midpoint formula : (x1 + x2)/2 , (y1 + y1)/2
(-3 + 9)/2 , (7 + 5)/2 = (6/2, 12/2) = (3,6) <==
Answer:
Step-by-step explanation:
4x+6<= -54
4x <= -60
x <= -15 [The point -15 is included, so it must be a solid dot]
----------------
5x + 7 > -18
5x > -25
x > -5 [The point -5 is NOT included, so it should be an empty dot.]
Solution C seems the best.
