How do I find the missing side of this similar triangle by using the are? Area for A is 17 mm^2 and B is 6800 mm^2

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

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
