Solve problem in photo 8th math

Consider the triangle (in which angle4 is present)

by angle sum property,

20 + 40 + angle4 = 180

60 + angle4 = 180

angle4 = 180 - 60

angle4 = 120

Also,

angle2 = 120 (vertically opposite angles)

angle1 + angle2 = 180 (linear pair)

angle1 + 120 = 180

angle1 = 180 - 120

angle1 = 60

Answer:

f(x)=43

Answer:

The slope of the given line is -4

Step-by-step explanation:

The formula of the slope of a line passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]

In the given figure

∵ The line passes through the points (-6, 5) and (-4, -3)

∴ x1 = -6 and y1 = 5

∴ x2 = -4 and y2 = -3

→ Substitute them in the formula of the slope above

∵ m = [tex]\frac{-3-5}{-4--6}[/tex]

∴ m = [tex]\frac{-8}{-4+6}[/tex]

∴ m = [tex]\frac{-8}{2}[/tex]

∴ m = -4

∴ The slope of the given line is -4

Answer:

The slope is -2.

Step-by-step explanation:

m=y2-y1/x2-x1            (also, y1-y2/x1-x2 is also true.)

=23-15/6-10                  m=15-23/10-6

= 8/-4                            =-8/4

=4/-2                             =-4/2

= 2/-1                             =-2/1

m=-2                             m=-2

Answer:

2

Step-by-step explanation:

Yeah its 2 I can explain but will be long but if want comment and I will post but most likely its 2

the perimeter of the field is 442

width=w

the length of the field is 9 yards less than quadruple W

L=4x - 9

the perimeter is P=2L+2W

you can plug in the values

P= 2(4w-9) + 2W

plug in 442 for P

442= 2(4w- 9) + 2W

442= 8w - 36 + 2W

478 =8w + 2W

478= 10W

47.8 is your answer!!!

Answer:

If two pairs of corresponding angles and the side between them are known to be congruent, the triangles are congruent. This shortcut is known as angle-side-angle (ASA). Another shortcut is angle-angle-side (AAS), where two pairs of angles and the non-included side are known to be congruent.

In ASA, two angles and one common side is equal and in AAS one not common side and two angles are equal.

Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes is represented by the symbol and consists of three connected vertices.

The ASA congruence means, there will be two corresponding angles and one side between them will be equal, then the triangles are congruent.

The AAS congruence means, there will be two corresponding angles and one side excluded from them will be equal, then the triangles are congruent.

Answer:

x = 12 (I took the FLVS assignment for 04.04, and I'll show you guys how to do this!)

Step-by-step explanation:

The team has completed 28 matches so far and has won 10 of them.

The current success rate is:

[tex]r=\frac{10}{28} *1.00=.35714[/tex]

(1.00 = 100% and .35714 = 35.714%)

We need the success rate to be 55%

Then the team must win a number of "x" matches, so:

[tex]r=\frac{10+x}{28+x} =0.55[/tex]

Now we solve the equation for x:

[tex]\frac{10+x}{28+x} =0.55[/tex]

[tex]10+x=0.55(28+x)[/tex](distributive property here!)

[tex]10+x=15.4+0.55x[/tex]

Now, move the 0.55x to the other side by subtracting it from both sides:

[tex]10+x-0.55x=15.4[/tex]

And move the 10 by doing the same thing (subtracting from both sides):

[tex]x-0.55x=15.4-10[/tex]

[tex]0.45x=5.4[/tex]

(You might ask: 15.4 - 10 = 5.4, but how do you get 0.45x out of x - 0.55x? Use Quick Math, and you should get the answer!)

[tex]x=\frac{5.4}{0.45}[/tex]

[tex]x = 12[/tex]

So, by following these steps, x = 12 is your answer!

The team must win 12 matches to have a success rate of 55%.

Hope this helps! Have a wonderful day!

Denominator is 180, Numerator is 120.

120/180 simplified is 2/3.
