Pls correct answer only 30 points what is the value of x? (same question for both pictures)

Step-by-step explanation:

1. Segments on one side of the angle bisector are proportional to those on the other side. We can use that fact with sums, as well

  (KT +VT/KT = (KY +VY)/KY

  (129.2 +57)/129.2 = x / 68 . . . . . substituting the given measures

Multiplying by 68 gives ...

  68·186.2/129.2 = x = 98 . . . mm

2. The top segment dimension on the left is 1/8 of the bottom segment dimension (9 cm = 1/8 · 72 cm). Since the top triangle is similar to the large triangle, the same ratio holds for the segments on the right:

  3x -20 = (1/8) · 56

  3x = 27 . . . . . . add 20

  x = 9 . . . . . . . . .divide by 3

hope i'm right lol
