Draw a diagram!  Lets say the width is x, then the length must be 2x.
   
                       Area = length x width
                          2x x  x    = 8sq meters
                         2x^2       = 8
                          x^2        =4
                           x      =  √4
                            x    = 2

we found the width the length is two times the width, making it 4 meters.

Answer:

  30°

Step-by-step explanation:

Consecutive interior angles are supplementary when the lines are parallel:

  2x +4x = 180°

  x = 180°/6

  x = 30°

_____

<em>Comment on units</em>

A lot of times the angles are assumed to be measured in degrees. Using that assumption, x=30 (degrees). When no units are specified, the angle measure defaults to radians. In radians, x = π/6. (We rarely see problems of this nature where the angles are expected to be measured in radians. More often, we see poorly edited questions where angles need to be assumed to be measured in degrees.)

The point B is at the centre of the circle. The pints P and Q are in the circumference of the circle. Calculate the area of the
Cerrena [4.2K]

Answer:

Area of the sector = 57.26295cm²

Step-by-step explanation:

Radius of the circle=9cm

π= 3.142

Angle at B= 81° ( opposite angle of a quadrilateral)

Area of the sector = πr² * 81/360

Area of the sector = 3.142 * 9*9 * 0.225

Area of the sector= 3.142*81*0.225

Area of the sector = 57.26295cm²

Answer:

<u>For 1 quart of orange juice:</u>

Calories =  448

Vitamin C =  387.6 mg

Carbohydrates  = 107.56 mg

Step-by-step explanation:

The following information is given about 1 CUP of orange juice:

<h2>Calories</h2><h3>112</h3><h2>Vitamin C</h2><h3>96.9 mg</h3><h2>Carbohydrates</h2><h3>26.89 mg</h3>

Now, we have to estimate the 3 values for 1 quart of orange juice. Remember, 4 cups is 1 quart, so we need to multiply each value by 4 to get the values for 1 quart.

Calories = 112 * 4 = 448

Vitamin C = 96.9 * 4 = 387.6 mg

Carbohydrates = 26.89 * 4 = 107.56 mg

Question 3 of 10
GalinKa [24]
<h3>Answer: D) Cannot be determined</h3>

Explanation:

Choice A isn't the answer because we don't know anything about the angles, so we can't use the AA (angle angle) Similarity theorem.

Choice B isn't the answer because we don't have info about all three pairs of sides (we only have two pairs of sides).

Choice C isn't the answer in a similar way choice A isn't either. We don't know anything about the angles, so we can't use the "A" in "SAS".

Choice D is the only thing left. It turns out we don't have enough info to be able to determine if the triangles are similar or not.
