Answer:

x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

8/4 = (8 +(x -1))/5

10 = x +7 . . . . . . . . . multiply by 5 and simplify

3 = x . . . . . . . . . subtract 7

Alternate solution

The short segments are also proportional:

(x -1)/(5 -4) = 8/4

x -1 = 2 . . . . simplify

x = 3 . . . . . . add 1
