The perimeter of the triangular park shown on the right is 13. 1. What is the missing length? The missing longth is (Simplify your answer.)

Missing side = 30

Step-by-step explanation:

13x - 1 = x - 1 +4x + 4

13x - 1 = 5x - 3

8x = 2

x = 4

Replace (x - 1) and (4x +4) with the x that we just found.  It should equal 3 and 20. Then replace the x in (13x - 1). It should equal 53. Then subtract 53 - 23.

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
