Need help with this important work please

Given:

IJ = v + 30

HK = v

To find:

The value of HK

Solution:

By Triangle mid-segment theorem:

If a segment joining midpoints of two sides of a triangle, then the segment is parallel to the third side and is half of its length.

Multiply by 2 on both sides.

Subtract v from both sides.

Therefore HK is 30.
