Pleasee help me with this anyone..

Step-by-step explanation:

You need to set up a proportion

Let x = NK

7/13 = x/56    Notice that the longest side of the small trapezoid is the denominator of the fraction  on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.

Cross multiply

13x = 7*56                Combine the right

13x = 392                 Divide by 13

x = 392/13

x = 30.15

NK = 30.15

30.2

Step-by-step explanation:

IJ is proportional to MN, which would give us 13/56. Next, JG is proportional to NK, which would give us 7/x. So, 13/56 = 7/x, 13x = 392, x = 30.15, which rounds to 30.2
