It means you have to find what number equals 36 but multiplying with 2
You’d have to try to get r on one side of the equation.
You can do that by subtracting 12 from both sides which would make it so
R = -9
THE ASNWER IS 0.9.
HOPES THIS HELPS YOU!!! CAN YOU MARK MINE AS BRAINLIEST????
We use the SSS congruence rule to prove the triangles to be congruent. From there, we then use CPCTC to show that angle I is congruent to angle L.
This is shown in the two column table (attached image below)
-----------
Notes:
SSS = side side side
CPCTC = corresponding parts of congruent triangles are congruent
