Plss correct answer only for 100 points the triangles are similar. what is the value of x?

13

Step-by-step explanation:

20/5 = 4

48/12 = 4

SF = 4

So

52/4 = 13

Step-by-step explanation:

If the triangles are similar, then the sides are in proportion:

          cross multiply

            divide both side by 20

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
