Answer:

see the attachment for the angle plots

Step-by-step explanation:

θ = 5.2 is a 4th-quadrant angle, shown with terminal ray "a" in the attached diagram.

θ' is the positive acute angle between the terminal ray of θ and the x-axis. It is shown in standard position using terminal ray "r" in the attached diagram. Its value is the difference between 5.2 radians and 2π ≈ 6.28 radians, about 1.08318531 radians. The diagram shows it rounded to 2 decimal places: 1.08 radians.

The width of a rectangle measures (8.4x + 2.2) centimeters, and its length

lorasvet [3.4K]

The algebraic expression that will represent the perimeter in centimeters of the given rectangle is: $(25.8x +11.2) $ cm$

Recall:

Perimeter of a rectangle = 2(L + W)

Given the following dimension of a rectangle:

width (W) = (8.4x + 2.2) cm
length (L) = (4.5x + 3.4) cm

To find the expression that represents the perimeter, plug in the given values into the formula for perimeter.

Thus:

Perimeter = $2((4.5x + 3.4) + (8.4x + 2.2))$

Open the bracket

Perimeter = $2(4.5x + 3.4 + 8.4x + 2.2)$

Add like terms together

Perimeter = $2(12.9x + 5.6)$

Multiply

Perimeter = $25.8x +11.2$

Therefore, the algebraic expression that will represent the perimeter in centimeters of the given rectangle is: $(25.8x +11.2) $ cm$
