Question

A is the midpoint of XY. use the diagram belowe to find x, XA, AY, and XY.

A to Y is 12x - 15
X to A is 9x
X=?
XA =?
AY =?
XY =?

Answer 1

9514 1404 393

Answer:

• XA = 45
• AY = 45
• XY = 90

Explanation:

Since A is the midpoint of XY, we have XA = AY:

9x = 12x -15

15 = 3x

5 = x

XA = 9x = 45

AY = 12x -15 = 60 -15 = 45

XY = 45 +45 = 90
