Answer:

x = 10\sqrt{3}

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos30° = \frac{\sqrt{3} }{2} , then

cos30° = \frac{adjacent}{hypotenuse} = \frac{x}{20} = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 20\sqrt{3} ( divide both sides by 2 )

x = 10\sqrt{3}

Cos=adjacent/hypotenuse
Cos30=x/20
x=cos30 *20

alberto knows that all the lines and rays are congruent to each other . he reasons that all segments must therefore be congruent
saw5 [17]

Answer:

Step-by-step explanation:

Alberto is correct in reasoning that all lines and rays are congruent to each other but incorrect in his reasoning about the line segments.

Line segments are equal in measure only when they are equal in length. They can have any orientation on a plane.

Since, AB = 3 units

CD = 4 units

Therefore, AB ≠ CD

Error in AB ≅ CD

Lelechka [254]

Store should sell about 31 bicycle for average price of $135 each bicycle.

Step-by-step explanation:

  • To find bike we need Algebra to solve the equation.
  • when x = 1 , Y = 135 *x
  • When x 2 , Y = 135 *2
  • Formula you could apply to go for break even y = 135*x
  • Bicycle store pays about $4200
  • Algebra used for every business and working to make easy task.
  • It takes about 31 bicycle a month to get into break even.
  • Every store needs break even to not incur lost.
  • Break even point is equilibrium between income and expenses.
