Answer:
AC ≈ 2.18
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan70° =
=
= 
Multiply both sides by AC
AC × tan70° = 6 ( divide both sides by tan70° )
AC =
≈ 2.18 ( to the nearest hundredth )
Y=10-4x/-4 => 3x=5-2(10-4x/-4)
3x=5+5-2x
5x=10
x=2 => 6+2y=5
2y=-1
y= -1/2
y=-0.5

If Log x (1 / 8) = - 3 / 2, then x is equal to
x- 3 / 2 = 1 / 8
The above equation may be rewritten as
x<span> - 3 / 2</span> = 1 / 23 = 2-3
(√x)-3 = 2-3
√x = 2 or x = 4
