| **Find the length of the segment AD, if the length of the segment BC = 3cm 4mm, the length of the segment AB is 75% of the segment BC, the segment CD is 50% of the segment BC.**

We translate the length of the BC segment into centimeters.

3 cm 4 mm = 3.4 cm.

Determine the length of the segment AB.

To do this, multiply the length of the BC segment by 75%.

Will be:

3.4 * 75% = 3.4 * 0.75 = 2.55 cm.

In a similar way, we determine the length of the segment CD.

3.4 * 50% = 3.4 * 0.5 = 1.7 cm.

Find the total length of the segment AD.

To do this, we sum up the value of the lengths of all the segments that make it up.

As a result, we get:

3.4 + 2.55 + 1.7 = 7.65 cm.

Answer: The segment AD is 7.65 cm.
