4x+2x+6 (which is ab plus bc)
6x+6 (the length of ac)
Since the two triangles are congruent, set the values of the legs equal to each other. x-y=x+2
-y=2
y=-2
Answer:P=2x + 2y + 8
Step-by-step explanation: Perimeter (p) =2L+ 2w
P= 2(x+5)+2(y-1)
Remove bracket
P=2x+ 10 +2y - 2
P=2x+2y+8
X= 270
simplify the equation using cross multiplication
