The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

If mâ abc = 70°, what is mâ abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so mâ abd = 110°. using the subtraction property of equality, 70 â 30 = 40, so mâ abd = 30°. using the angle addition postulate, 40 + mâ abd = 70. so, mâ abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = mâ abd. so, mâ abd = 110° using the addition property of equality.
