A relationship between two variables in which one is a constant multiple of the other. </span>
AK = 640
Δ ABC and ΔFJK are similar. They are small triangles.
ΔCDF is the big triangle.
640 / 2 = 320 m= CF
AC & FK= 320/2 = 160 m each
2AC = CF = 2FK
2(160) = 320 = 2(160)
BG = 20 m
20/160 = x / 320
20*320 = 160x
6400 = 160x
6400/160 = x
40 = x
Area of CDF = (40 m * 320 m)/2 = 12,800 / 2= 6,400 m²
The answer would be x= 4,-4
17. Its answer C i wil tell you the other one in a sec
Just find out 5% of 59.95, then just add that to 59.95. 2.99 is 5% of 59.95, 2.99+59.95=62.94
