Answer:

  • x = 150
  • y = 4

Step-by-step explanation:

The ratio of areas of similar figures is the square of the scale factor. Then we have ...

  larger/smaller = √(6800/17) = √400 = 20

The dimensions of the larger triangle are 20 times those of the smaller triangle.

  x mm = 20(7.5 mm)

  x = 150

__

  20(y mm) = 80 mm

  y = 4
