Answer:

17 A...... x=56

17 B...... x=4

Step-by-step explanation:

lets start with 124

f-a is 180 degrees

we know 124 so 180-124

56 degrees under the 124

c-e is also 180 degrees

we know 6x

lets say the other degree is y

so 180=6x+y

but the y is inside the triangele, which is what we need

so the angles added up inside the triangle is

56+2x+y=180 degrees because thats what the angle measurements equal for a triangle

so 56+2x+y=180

subtract 56 from both sides

2x+y=124

divide both sides by 2

x+y=62

6x+y=180

x+y=30

124+x=180

x=56

x+y=62

56+y=62

y=6

x(56)+y(6)=62

2. problem

triangle angles must equal 180 degrees

f angle... lets say is y

so

4x+65+y=180

subtract 65 from both sides

4x+y=115

get x by itself

so -y from both sides

Answer:

m∠8 = 49°

Step-by-step explanation:

∠7 and ∠8 are same-side interior angles.

Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.

Let's use the variable 'x' to represent the unknown measure of angle ∠8.

[tex]131 +x=180[/tex]

[tex]131-131=0[/tex] (cancels itself out)

[tex]180-131=49[/tex]

[tex]x=49[/tex]

Therefore, the measure of ∠8 is 49°.

 Rules for the operations of the functions state,

Option (2) is the correct option.

    Now we will apply this operation in each option to check (f o g)(x) = x

Option (1)

f(x) = x² and g(x) = [tex]\frac{1}{x}[/tex]

Therefore, (f o g)(x) = f[g(x)]

                                = [tex]\frac{1}{x^2}[/tex]

False.

Option (2)

f(x) = [tex]\frac{2}{x}[/tex] and g(x) =

(f o g)(x) = [tex]\frac{2}{\frac{2}{x}}[/tex]

             = [tex]\frac{2}{1}\times \frac{x}{2}[/tex]

             = x

True.

Option (3)

f(x) = [tex]\frac{x-2}{3}[/tex] and [tex]g(x) = 2-3x[/tex]

(f o g)(x) = f[g(x)]

             = [tex]\frac{2-3x-2}{3}[/tex]

             = -x

False.

Option (4)

f(x) = [tex]\frac{1}{2x}-2[/tex] and [tex]g(x)=\frac{1}{2x}+2[/tex]

(f o g)(x) = f[g(x)

             = [tex]\frac{1}{2(\frac{1}{2x}+2)}-2[/tex]

             = [tex]\frac{1}{\frac{1}{x}+4}-2[/tex]

             = [tex]\frac{x}{1+4x}-2[/tex]

             = [tex]\frac{x-2(4x+1)}{4x+1}[/tex]

             = [tex]\frac{x-8x-2}{4x+1}[/tex]

             = [tex]-\frac{7x+2}{4x+1}[/tex]

False.

                Therefore, Option (2) is the correct option.

Answer:

t = 41.6 (the 6 is repeating)

Step-by-step explanation:

2.5t + 350 = 3t + 225

Subtract 2.5t from both sides to get:

350 = 3t + 225

Now subtract 225 from both sides to get:

125 = 3t

Divide both sides by three.

t = 41.6 (the 6 is repeating)
