To find: The length of XY .
Answer to Problem 3CE
The length of XY is 14 units.
Explanation of Solution
Given:
The triangle is shown below:
Side TN is 7 units. M , N and T are the midpoints.
Calculation:
Consider in
Angle XMT and XYZ are the corresponding
Consider in triangles NMY and ZXY .
Angle YNM and YZX are the corresponding angles. Hence, line NM and ZX or ZT are parallel to each other.
Thus, MNZT is parallelogram.
Similarly TNXM is also a parallelogram.
The side XY is calculated as follows:
Thus, the length of XY is 14 units.
