Answer:

x is 2 and y is 2✓3

Step-by-step explanation:

this is because of the 30 60 90 theorem

so 1 is n

and x has to be 2n so it is 2

and y is n√3 so it's 2√3

Answer:

<em>x = 2 , y = √3 </em>

Step-by-step explanation:

In right angled Δ, the leg against of 30° angle equals half of length of hypotenuse ⇒ <em>x = 2</em> and <em>y</em> = √(4 - 1) <em>= √3</em>

In an average of 65 minutes if a train stops at three stations for two minutes each and the distance is 115 miles between stops
larisa86 [58]

Answer:

117mph

Step-by-step explanation:

Given that

Total number of stations= 3

Total average time of journey of train = 65

total stop time at three stations = 3×2 =6 min

Total distance between stops = 115 miles

as we can see

Total time train was travelling = 65- 6 =59 min

so, average speed of train can be calculated as:

Average Speed = \frac{Distance -travelled-between -stations}{Total-time-the-train-travelled}

Average Speed = \frac{115}{59} =1.95 miles/minute

To convert this speed into miles per hour (mph) multiply the above speed by 60

Average speed = 60×1.95 =117 mph

So the average speed of train is 117mph.

What are the coordinates of the image of vertex G after a reflection across the line y = x?​
Yuliya22 [10]

Answer:

The coordinates of the image of vertex G are (-5, 4)

Step-by-step explanation:

Let us revise some cases of reflection

  • If the point (x, y) reflected across the x-axis , then its image is (x, -y)
  • If the point (x, y) reflected across the y-axis , then its image is (-x, y)
  • If the point (x, y) reflected across the line y = x , then its image is (y, x)
  • If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)

From the given figure

∵ The line of the reflection is y = x

→ That means we will switch the coordinates of the point to find its image

∵ The coordinates of vertex G are (4, -5)

∴ The x-coordinate = 4 and the y-coordinate = -5

→ Switch the two coordinates

∴ The coordinates of its image G' are (-5, 4)

∴ The coordinates of the image of vertex G are (-5, 4)
