It’s 128
the angle opposite 38 is 52
so the angle on the line with x is also 52
so x is 180-52=128

wolverine [178]

Answer:

There's only 1 step. It is the second one, "Multiply 4 by 5 and multiply 4 by 3x"

Step-by-step explanation:

4(5 - 3x) =

4(5) - 4(3x) =

20 - 12x

You can't simplify further, so the second one is the right answer

The coordinates of vertices of quadrilateral questions in picture please help
frutty [35]

Answer:

5.  (x, y) ⇒ (-x, y) — see attached for the diagram

6.  (x, y) ⇒ (x+3, y+5)

7.  dilation

Step-by-step explanation:

5. A point reflected across the y-axis will have the same y-value, but the opposite x-value. The transformation rule is ...

  (x, y) ⇒ (-x, y)

___

6. A horizontal translation by "h" adds the value "h" to every x-coordinate. A vertical translation by "k" adds the value "k" to every y-coordinate. Then a translation by (h, k) will give rise to the rule ...

  (x, y) ⇒ (x+h, y+k)

Your translation right 3 and up 5 will give the rule

  (x, y) ⇒ (x+3, y+5)

___

7. Any translation, rotation, or reflection is a "rigid" transformation that preserves all lengths and angles. Hence the transformed figure is congruent to the original.

When a figure is dilated, its dimensions change. It is no longer congruent to the original. (If the dilation is the same in x- and y-directions, then the figures are <em>similar</em>, but not congruent.)

Draw line segment AB - 7cm and bisect it using compass.​
Fed [463]

Answer:

<h2>Your answer is in picture.</h2><h3>Steps of construction: </h3>

(i) Draw a line segment AB = 7 cm.

(ii) With A as centre and radius more than half of AB, draw arcs, one on each side of AB.

(iii) With B as centre and same radius as before, draw arcs, cutting the previously drawn arcs at X and Y respectively.

(iv) Now join XY, meeting AB at O.

Thus, XY is the perpendicular bisector of AB.

Step-by-step explanation:

A number decreased by 23 is 44. Find the number.
Hoochie [10]

Answer:

A

Step-by-step explanation:

The number is decreased by 23 which means 23 is subtracted from the number.

let the number be x, then

x - 23 = 44 ( add 23 to both sides )

x = 67

The number is 67

There are 8 roll of carpet each carpet roll i 6 yard longhow long are the 8 roll in feet
vlabodo [156]

The given 8 rolls will have a length of 144 feet or in other words, they will be 144 feet long.

Here, we are given that thee are 8 rolls of carpet and each roll is 6 yards long.

We know that the conversion factor of yards to feet is as follows-

1 yard = 3 feet

Thus, 6 yards = (6 × 3) feet

= 18 feet

⇒ each roll of carpet is 18 feet long

Since there are a total of 8 carpets given, the length of all the 8 rolls will be given as follows-

18 × 8

= 144

Thus, we find that the given 8 rolls will have a length of 144 feet or they will be 144 feet long.
