8. first 12 bags for 54m^{2}
[/tex]
54 ÷ 12 = 4.5
we know: 1 bag for 4.5m^2
36 ÷ 4.5 = 8
so 36m^2 we must use 8 bags

Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft
I hope this helps
1/2d+6=1/2(d+12)
Leaving us with 0.5 or 1/2
(x, y) = (-3, 4) hope this helps!
