Homework Equations
The Attempt at a Solution
R=BD
OR
R=A+C
In this problem, I figured that because of the way the arrows are pointing R+D=B which you can then simplify to R=BD. However, this is not an answer to the problem.
I then tried using the other triangle with R. Because of the way the arrows are pointing, I figured that A+C=R. However, this is also not a solution to the problem.
