Answer:

GA=17

Step-by-step explanation:

As A, B, C are the midpoints of the sides of AGHJ,

so GH= 2(CB)

⇒7z-1= 2(4z-3)

⇒7z-1= 8z-6

⇒7z-8z= -6+1

⇒-7= -5

z=5

so GA=CB

⇒GA= 4(5)-3= 17

hope it helps...

have a great day

Answer: D) 10

============================================================

Explanation:

I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.

So,

DE = 2*(MN)

3x-2 = 2*(x+4)

3x-2 = 2x+8

3x-2x = 8+2

x = 10

M+m+z/3=3m
m+m+z=9m
2m+z=9m
z=7m
m+m+7m/3=3m
9m=9m
m=1
1+1+z/3=3
2+z=9
z=7
