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

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
