Answer:
RT = 23
Step-by-step explanation:
We will have a line that essentially goes like this:
R-----S-----T
The distance from R to S is 12 units.
The distance from S to T is 11 units.
We need to find the distance from R to T.
R is the starting point and T is the ending point.
To find the total distance, we can add both line lengths.
12 + 11 = 23 units
Best of Luck!
