What is the value of x?
Please help. I will reward for correct answers.

Answer 1

x = 98 mm

Explanation:

The angle bisector divides the triangle into proportional parts. That is ...

VY/YK = VT/KT

This means that ...

VK/YK = (VT+KT)/KT

Multiplying by YK gives ...

VK = x = YK · (VT +KT)/KT

x = (68 mm) · (57 +129.2)/129.2 = 98 mm
