Segment AB has point A located at (5, 4). If the distance from A to B is 7 units, which of the following could be used to calculate the coordinates for point B?
07 = V(x+4)2 + (y + 5)2
07= V(x+5)2 + (y+4)2
07 = V(x - 4)2 + (y – 5)2
07 = V(x - 5)2 + (7-4)2

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c
