-(3x-2)=-4(x+1)-4
-3x+2=-4x-4-4
-3x+4x=-4-4-2
x=-10

Answer:B
Step-by-step explanation:
Answer:
tan56°
Step-by-step explanation:
The Addition identity for tangent ratio is
tan(x + y) =
, thus
= tan(24 + 32)° = tan56°
Work backwards with pythagoras' theorem:
c^2=a^2+b^2
Here, a and b both equal to x. Therefore, you can write this as 8^2=2x^2. So 64=2x^2. Sqrt on both sides to give you 8=2x, hence x=4. However I must warn you that this working out may have a flaw, as I found that x actually equals to 5.66
