In polar coordinates, the axis determined by theta=0 is called the positive x-axis or horizontal axis.

To add, in mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction.

Can anyone help me?plps

stepladder [879]

Answer:

42.5°

Step-by-step explanation:

Reference angle = θ

Side opposite to θ = 2.7

Hypotenuse = 4

Applying trigonometric ratio, we have:

$sin (\theta) = \frac{opp}{hyp} = \frac{2.7}{4}$

$sin (\theta) = 0.675$

$\theta = sin^{-1}(0.675)$

$\theta = 42.4541502$

θ = 42.5° (nearest tenth)

Which graph shows the new position of the rectangle after a translation? Rectangle with coordinates: (0, negative 1), (0, negati

Scrat [10]

As you can see in the screenshot, once you plot the points for each rectangle, it becomes easier to see what's happening. In the first transformation, the rectangle is translated or slid. In the next 2 transformations, the rectangle is rotated. In the last transformation, the rectangle is dilated or shrunk. The first rectangle is the only translation.
