Perform the indicated operations:

Angle RZT=110 Angle RZS=3s Angle TZS=8s What are angles RZS and TZS?

nekit [7.7K]

Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180. Thus, we have:

110+3s+8s=180

Simplifying, we have:

11s=70

Dividing by 11, we see that:

s=70/11

Therefore, RZS=3s=210/11, and TZS=8s=560/11.

The graph shows the dilation of ΔABC with the origin as its center. Which rule describes this transformation? A) (x, y) → (2x, 2

podryga [215]

Note: Since, you have not added the graph. So, I will give you a general overview of the concept of dilation, the understanding of which will make you clear your concept.

Step-by-step explanation:

We know that a dilation is the kind of transformation which produces an image which has the same shape as the original object, but having a different size.

Here are some key factors regarding dilation:

Enlargement occurs when a dilation does create a larger image.

Reduction occurs when a dilation does create a smaller image.

A dilation shrinks or stretches the original object.
If the scale factor > 1, the image will be a stretch (enlargement)
If the scale factor is between 0 and 1, the image will be shrunk (reduction)
If the scale factor = 1, the original object and the image will be congruent

Here is the impact of dilation when (x, y) → (2x, 2y):

Dilation with scale factor 2, will have the rule as (x, y) → (2x, 2y). The image will be a stretch (enlargement) as the scale factor > 1.
The location of the new coordinates of the image can be obtained by multiplying the coordinates of the original figure by 2.

For example, the coordinates of the image of a point A(4, 8) will be A'(2×4, 2×8) or A'(8, 16) after the dilation of scale 2 at the origin.

Here is the impact of dilation when (x, y) → (0.5x, 0.5y):

Dilation with scale factor 0.5, will have the rule as (x, y) → (0.5x, 0.5y). The image will be shrunk (reduction) as the scale factor < 1.
The location of the new coordinates of the image can be obtained by multiplying the coordinates of the original figure by 0.5.

For example, the coordinates of the image of a point A(4, 8) will be A'(0.5×4, 0.5×8) or A'(2, 4) after the dilation of scale 0.5 at the origin.

*PLS HELP* I need help on this and please provide an explanation

expeople1 [14]

Answer:

Step-by-step explanation:

Value of x

<h3>Given:-</h3>

46° and (5x - 1)° are complementary angles

<h3>Solution:-</h3>

As we know,

Complementary angles:

The angles whose sum results to 90° are known as the complementary angles.

So,

46° + (5x - 1)° = 90°

[Since complementary angles]

=> 46 + 5x - 1 = 90

[On Simplification]

=> 45 + 5x = 90

[On subtracting both sides with 45]

=> 45 + 5x - 45 = 90 - 45

[On Simplification]

=> 5x = 45

[On dividing both sides with 5]

$= > \frac{5x}{5} = \frac{45}{5}$

[On Simplification]

=> x = 9

Hence, required value of x = 9 (Ans)
