Answer:
n = 15.5
Step-by-step explanation:
(4+n)/(43+n) =1/3
3(4+n)= 1*(43 + n)
12 + 3n = 43 + n
3n - n = 43 - 12
2n = 31
n = 31/2= 15.5
Answer:
Equation for x: 3x - 6 = 
x = 9
CD = 17
GH = 21
Step-by-step explanation:
The midsegment formula for a trapezoid is
GH = 
3x - 6 = 
6x - 12 = 2x + 24
4x = 36
x = 9
CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17
GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21
