answer is A. cosine

Step-by-step explanation:

Answer:

[tex]x = 71[/tex]

Step-by-step explanation:

The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.

Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.

[tex]180 - 40 - 31 = 109[/tex]

So the missing angle is 109°. Now we can find the value of x.

We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.

[tex]180 - 109 = 71[/tex]

Now we know x is 71

Step-by-step

measure angle 1 is corresponding to measure angle 5

measure angle 5= measure angle 1= 71*

measure angle 5 + measure angle 8 = 180*

71*+ measure angle 8=180*

measure angle 8=109

Answer:

[tex]m\angle5 = 71\degree^{\circ}[/tex],

[tex]m\angle8=109^{\circ}[/tex]

Step-by-step explanation:

Given that [tex]a[/tex] and [tex]b[/tex] are parallel and [tex]m\angle1=71^{\circ}[/tex]:

[tex]m\angle5 = 71^{\circ}[/tex] (Corresponding angles are equal when [tex]a\parallel b[/tex] )

[tex]m\angle8+m\angle5=180^{\circ}[/tex] (The two angles make up the angle of a straight line: [tex]180^{\circ}[/tex]

[tex]m\angle8 + 71^{\circ} = 180^{\circ}[/tex]

[tex]m\angle8 = 109^{\circ}[/tex]

[tex]\therefore m\angle5=71^{\circ};m\angle8=109^{\circ}[/tex]

Answer:

x=0 or x=4

Step-by-step explanation:

Lets Solve!

First we need to factor the left side of the equation. Both terms include x.

[tex]x^2-4x =0[/tex]

[tex]x(x-4) =0[/tex]

If we multiplied x by (x-4) we would be back at [tex]x^2-4x =0[/tex].

Set factors equal to 0.

x=0 or x−4=0

x=0 or x=4

Woohoo! Brainliest Appretiated! Hope I helped!

Answer:

[tex]x=0,4[/tex]

Step-by-step explanation:

Factor out the common terms from x²-4x. You can factor out x:

[tex]x(x-4)=0[/tex]

Multiplication can be seen as (_)(_). Rewrite:

[tex](x)(x-4)=0[/tex]

Set both equal to 0:

[tex]x=0\\\\x-4=0[/tex]

Simplify the second equation:

[tex]x-4=0\\\\x-4+4=0+4\\\\x=4[/tex]

So, x=0 or x=4

Answer:

[tex]-\frac{1}{5} x+b[/tex] (b can equal any number- you can use 3)

Step-by-step explanation:

To find the slope, you take mx (in this case 5x), get the number by itself, flip the sign, then get the reciprocal.

5 -> -5 -> [tex]-\frac{1}{5}[/tex]

Answer:

128 girls

Step-by-step explanation:

The ratio of boys to girls is 6 to 8. We need to find how many girls there are if there are 96 boys in the camp. One way to solve this is by using cross multiplication:

[tex]\frac{6}{8}[/tex] = [tex]\frac{96}{x}[/tex]

multiply the 6 by the x: 6x

multiply 8 by 96: 768

6x = 768

divide both sides of the equation by 6 to isolate the x:

6x/6 = 768/6

x = 128

When there are 96 boys in camp, there will be 128 girls.

Answer:

6/8=96/x

Answer:

A) ∠1

Step-by-step explanation:

They are corresponding angles meaning that they are congruent to each other.

The congruent angle of angle 5 is [tex]\angle1[/tex]

When a transversal line cuts two parallel lines. the, corresponding and alternate angles are equal.

From given figure, It is observed that,

Corresponding angles are,

      [tex]\angle1 =\angle5,\angle3=\angle7[/tex]

Answer:

D.) j

Step-by-step explanation:

J because if in one month there is $32 and then in 2 months there are $64 its multiplying 32 times 2 and that gets 64 then 64 plus 32 is 96 then plus 32 again and that gives you 128. Its multiplying 32 times 2 then 32 times 3 then 32 times 4 and that gives you your answer.

Answer:

in -7y y is variable and -7 is Constant

Step-by-step explanation:

Constant: A number that cannot change its value. In the expression 2x+4y−9 , the term 9 is a constant. Like Terms: Terms that contain the same variables such as 2m , 6m or 3xy and 7xy

variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set.
