Sagot :

Step-by-step explanation:

ABC and CDE are similar triangles.

similar shapes means that both shapes have the same angles. and : that there is one scaling factor for all lines of one of the shapes to calculate the lengths of the lines of the other shape.

we see that all the other sides of ABC are scaled 2:1 to the corresponding sides of CDE. that means the sides of ABC are twice a long as the sides of CDE.

the same scaling factor has to apply to AB vs. DE.

therefore,

11x - 25 = 2(4x + 1) = 8x + 2

3x = 27

x = 9

DE = 4x + 1 = 4×9 + 1 = 36 + 1 = 37
