Use the cosine formula
Cos(angle) = adjacent/ hypotenuse
cos(30) = x/8
Cos(30) can be written as sqrt(3)/2
Now you have :
sqrt(3)/2 = x/8
Multiply both sides by 8:
X = sqrt(3)/2 x 8
Simplify:
X = 4sqrt(3)
Answer:
9
Step-by-step explanation:
x² − 36 = 5x
x² − 5x − 36 = 0
(x − 9) (x + 4) = 0
x = 9 or -4
Length of a circumference=2πr
r=radius=6 feet.
lengt of this circumference=2π6 feet=12π feet.
1 circumference=360º; then:
360º-------------------12π feet
6º---------------------- x
360º * x=6º * 12π feet
x=(6º * 12π feet) / 360º=π/30 feet (≈0,105 feet).
Solution: π/30 feet
Answer: £3885.71
Step-by-step explanation:
Let x be salary
Holding pay = 17.5% of x = 680.00
X = 680/0.175 = 3885.71
