that is confusing i have no idea
Cos²(15°) - sin²(15°) = cos(15° * 2) = √(3/2 so this is the answer by using apropriate formula double angle identity
So for this equation you would divide 150 by 0.4
150/0.4= 375 poles
Answer:
X= 12
Step-by-step explanation:
Simplifying
4x + -2 = 46
Reorder the terms:
-2 + 4x = 46
Solving
-2 + 4x = 46
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + 4x = 46 + 2
Combine like terms: -2 + 2 = 0
0 + 4x = 46 + 2
4x = 46 + 2
Combine like terms: 46 + 2 = 48
4x = 48
Divide each side by '4'.
x = 12
Simplifying
x = 12
