Do you mean the length of the cable?
If so, it would be 13.42ft.
Take the cable as the hypotenuse, and add the squares of 12 and 6 then squareroot them.
Answer:
Solve for x and justify each step with a reason: 3(x - 2) + 5x = 9x - 24
Steps:
Justification (Reasons):
3(x - 2) + 5x = 9x - 24
Given
3x - 6 + 5x = 9x - 24
Distributive Property
3x + 5x - 6 = 9x - 24
Commutative Property of Addition
8x - 6 = 9x - 24
Combine Like Terms
8x - 8x - 6 = 9x - 8x - 24
Subtraction Property of Equality
0 - 6 = x - 24
Additive Inverse Property (left)
Combine Like Terms (right)
-6 = x - 24
Additive Identity Property
-6 + 24 = x - 24 + 24
Addition Property of Equality
18 = x + 0
Addition (left)
Additive Inverse Property (right)
18 = x
Additive Identity Property
The justification method shown above is an example of one method.
There are other justification methods that are deemed acceptable.

8x + 9 = 42
8x +(9-9)=42-9
8x=33

Answer:
90°
Step-by-step explanation:
Circle C has radius √36 = 6
Circle D has radius √18 = 3√2
As the D radius intersecting either point of tangency, does so at a right angle.
The half angle θ between the tangents is
sinθ = 3√2 / 6 = ½√2
θ = 45°
so the angle between the tangents is 2(45) = 90°
