X° + 123° + 90° = 360° (angles at a point)
x° = 360° - 90° -123°
x° = 147°

The answer of x is 147°

Hope I can help you :)

Which sequence of transformations will produce similar but not congruent figures?

RoseWind [281]

A dilation would produce<span> a </span>similar figure. Therefore, the sequence of transformations that will produce a similar but not congruent figures would be the first and the third option. Figure TUVWX is dilated by a scale factor of 6 and then rotated 90° counterclockwise around the origin; and f<span>igure TUVWX is reflected across the x-axis and dilated by a scale factor of 7. Hope this answers your question.</span>

Radda [10]

Answer:

(B) the mean is less than the mode and less than the median.

Step-by-step explanation:

Mean, Median, Mode is used to calculate the central tendency of the distribution.

Mean is defined as,

$Mean = \dfrac{Sum of all observation}{Total number of observation}\\ \ \ \ \ \ \ \ \ = \dfrac{4+1+7+6+8+2+7}{7}$

∴ Mean = 5

Median is the middle observation of the distribution after arranging it in ascending or descending order.

So, arranging distribution in ascending order we get,

$1, $2, $4, $6, $7, $7, $8

Also, a number of observation is 7 which is an odd number.

Hence, $Median = (\frac{Number of observation + 1}{2})^{th} term$

⇒ $Median = (\frac{7 + 1}{2})^{th} term$

⇒ Median = 4th term = 6

Mode is the observation which has highest frequency.

Here, only $7 is repeated 2 times.

Hence, Mode = 7.

Hence, we see that Mean < Median < Mode

So, Option (B) is correct i.e. mean is less than the mode and less than the median.

The perimeter of the triangle will be 41ft

<h3>The perimeter of a triangle</h3>

The perimeter of a triangle is the sum of all the sides of the triangle

From the given triangle, we need to get the third sidee firse as shown:

h² = 12² + 12²

h² = 144 + 144

h² = 288

h = 17ft

Perimeter = 12 + 12 + 17

Perimeter = 41ft

Hence the perimeter of the triangle will be 41ft

-2x+9y=5 when x equals 11

dimaraw [331]

You would multiply -2 by 11 and get -22. Next your equation would equal to -22+9y=5. You simply subtract -22 from both sides, which basically means you're adding 22. Next your equation would be 9y=27. All that is left to do is divide both sides by 9, and you get that y is equal to 3.
