Answer: x=1.6

Step-by-step explanation:

1.1=-8.5+6x

+8.5 +8.5 (add 8.5 on each side)

9.9=6x

Divide by 6 on each side to leave the x by itself

x=1.6

Answer:

x= 1.6

Step-by-step explanation:.

1.1=−8.5+6x

Step 1: Simplify both sides of the equation.

1.1=6x−8.5

Step 2: Flip the equation.

6x−8.5=1.1

Step 3: Add 8.5 to both sides.

6x−8.5+8.5=1.1+8.5

6x=9.6

Step 4: Divide both sides by 6.

6x /6 =  9.6/ 6

x=1.6

Answer:

Step-by-step explanation:

In order for a triangle to be a right triangle, it has to fit into Pythagorean's Theorem:

[tex]a^2+b^2=c^2[/tex] where c is the hypotenuse.

We need to figure out which is the longest side in each of those triangles and that is the hypotenuse.

In the first set, the sqrt of 443 is 21.04, but that is not the longest side; 24 is. So the Theorem formula for that is:

[tex]\sqrt{443}^2+17^2=24^2[/tex] which gives us

443 + 289 = 576, but 732 does not equal 576, so that one is not right.

In the second set, the sqrt of 725 is the longest side, so that formula is:

[tex]\sqrt{725}^2=14^2+23^2[/tex] which gives us

725 = 196 + 529, and 725 does equal 725, so that one is right.

In the third set, the sqrt of 890 is the longest side, so:

[tex]\sqrt{890}^2=19^2+23^2[/tex], which gives us

890 = 361 + 529, and 890 = 890, so that is a right triangle as well. That's how you know those are right, compared to the first one that is not.

the answer is 9√3

sin60°= p/h

√3/2 = x/18

by cross multiplication we get

18√3=2x

therefore: x=9√3

Step-by-step explanation:

Answer:

y=16 bc 17 -16 =1 which if u do backward equals the same thing

and all together is

18y+1 and just leave it like that dont touch the numbers or anything bc you cant take a 1 and join it with a variable

you can only join numbers with numbers and variables with variables

Opening Exercise

The original triangle, labeled A, has been reflected across the first line, resulting in the image labeled B. Reflect the image across the second line. Carlos looked at the image of the reflection across the second line and said, “That’s not the image of triangle A after two reflections; that’s the image of triangle A after a rotation!” Do you agree? Why or why not?

Discussion

When you reflect a figure across a line, the original figure and its image share a line of symmetry, which we have called the line of reflection. When you reflect a figure across a line and then reflect the image across a line that intersects the first line, your final image is a rotation of the original figure. The center of rotation is the point at which the two lines of reflection intersect. The angle of rotation is determined by connecting the center of rotation to a pair of corresponding vertices on the original figure and the final image. The figure above is a 210° rotation (or 150° clockwise rotation).

Exploratory Challenge

Line of symmetry of a figure: This is an isosceles triangle. By definition, an isosceles triangle has at least two congruent sides. A line of symmetry of the triangle can be drawn from the top vertex to the midpoint of the base, decomposing the original triangle into two congruent right triangles. This line of symmetry can be thought of as a reflection across itself that takes the isosceles triangle to itself. Every point of the triangle on one side of the line of symmetry has a corresponding point on the triangle on the other side of the line of symmetry, given by reflecting the point across the line. In particular, the line of symmetry is equidistant from all corresponding pairs of points. Another way of thinking about line symmetry is that a figure has line symmetry if there exists a line (or lines) such that the image of the figure when reflected over the line is itself.

Does every figure have a line of symmetry?

Answer:

16 cm²

Step-by-step explanation:

The dimension of rectangle = 7cm by 4 cm

The Area of the greatest square that can be cut from the rectangle :

The dimension has to be the Same to form a square :

Hence, the greatest width = 4cm

Therefore, taking the length also as 4cm

Area of square = side length²

Greatest area of square that can be cut = 4² = 16cm²

Answer:

(6x + 3) + (7x - 44) = 180

6x + 3 + 7x - 44 = 180

13x - 41 = 180

13x = 221

adjacent x = 17

Answer:

<BED and <DEA, <AEC and <BEC

Step-by-step explanation:

Supplementary angles are two angles whose degree measures add up to 180 degrees. In other words, two angles that form a straight line.

In the given picture that is: <BED and <DEA, together they form line AB.

Another two supplementary angles in the given image are: <AEC and <BEC, they form line AB, from a different perspective.

Answer:

38° because the other two are cm? also you haven't linked a photo so I can't work out angle A

Step-by-step explanation:

GIven data

Point 1= (8,3)

x1= 8

y1= 3

Point 2=  (2,7)​

x2= 2

y2= 7

The expression for the distance between two points is given as

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((2-8)²+(7-3)²)

d=√((-6)²+(4)²)

d=√36+16

d=√52

d= 7.21

Hence the distance between the points is 7.21 units

Answer:

4) 8

Step-by-step explanation:

In the formula y = mx + b, m is the slope and b is the y-intercept

m = 8

b = -1

If m = 8 and m is the slope, then the slope is 8

Answer:

x = 139 degrees

Step-by-step explanation:

first, find what the missing interior angle is:

add the known angles:

90 + 49 = 139

subtract the sum from 180:

180 - 139 = 41

now to solve for x, take 180 and subtract 41:

180 - 41 = 139

x = 139 degrees
