Хорды кд и вр пересекаются в точке а так что ак 7см да-4см ав 14см найти вр

To find VR, we can use the intersecting chords theorem, which states that:

AV * BV = CV * DV

Given that AK = 7 cm, AD = 4 cm, and AV = 14 cm, we can set up the following equation:

14 * BV = CV * 4

Now, we need to know the lengths of BV and CV in order to find VR. Is there any additional information you have on those measurements?
