The measure of segment ST is 12
The point where two lines meet or intersect is known as an angle.
If Point S is between points R and T and P is the midpoint, then the following are true;
Given the following segments
RT = 20
PS = 4
Substitute into the given expression
2(4) + ST = 20
8 + ST = 20
ST = 20 - 8
ST = 12
Hence the measure of segment ST is 12.
