The problem is as follows: Given: AC is equivalent to BD. Angle Relationship Proofs. This online calculator will compute and plot the distance and midpointof a line segment. $A(x_A, y_A)$ and $B(x_B, y_B)$, we use formula: Find distance between points $A(3, -4)$ and $B(-1, 3)$. Those calculators draw a sketch of the calculated shape: Regular N-gon, Triangle, Convex Quadrilateral, Concave Quadrilateral, Antiparallelogram, House-Shaped Pentagon, Trapezoid, Simple Polygon, Ellipse, Lune. 3x 4x - 6_________________________________X A Y, The trick in this problem is to see that if A is the midpoint, then XA = AY.Since XA = AY, 3x = 4x - 6, Subtract 3x from both sides.3x - 3x = 4x - 3x - 60 = x - 6Add 6 to both sides of the equation.0 + 6 = x - 6 + 66 = x, To compute XA, you can either use 3x or 4x - 6Using 3x, we get XA = AY = 3 Ã 6 = 16, Using 4x - 6, we get XA = AY = 3 Ã 6 - 6 = 18 - 6 = 12.
