Find . I think it has to do with the short side being 2/3 the long side but idk?

The value of x is 10.5

Solution:

Given RST is a triangle.

BC bisect the triangle RST.

SC = CR and SB = BT

This implies that BC is the mid-segment of ΔRST.

By mid-segment theorem:

Mid-segment = Half of the parallel side

Multiply by 2 on both sides.

Add 10 on both sides.

Subtract x from both sides.

Divide by 2 on both sides.

x = 10.5

The value of x is 10.5
