Step-by-step explanation:

Answer:

130 degrees

Step-by-step explanation

Angle 6 is 130 degrees because it has a vertical angle relationship with the angle measure of 130 degree

Angle 6 and 2 are equal because of the corresponding angle relationship

OR

The angle measure of 130 degrees have an alternate interior angle relationship with angle 2 which makes them equal

Therefore angle 2 is 130

Hope it helped :))

Step-by-step explanation:

Answer:

- 3 ( 2x+1 ) 20

8x+5

_____________

8x+5×20 -3 ( 2×12.5+1 )

8×=100 -3 ( 25+1 )

100÷8= 12.5 -3 ( 26 )

×= 12.5

-3 ( 26 )

-3×2 + -3×6 = -6+ -18 = -24

-24

Answer:

The first one

Step-by-step explanation:

Its just playing with the signs, its not ____ and equal to so the last two arent it (because of the empty circle) and its greater than -1 so its number 1.

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex]

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

[tex]\sqrt{2}[/tex] x = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )

x = 4

Step-by-step explanation:

Answer:

yea its the last one

Step-by-step explanation:

its pretty straight forward what the answer is

Step-by-step explanation:

[tex]x = y \\ 2 \sqrt{14} = x \sqrt{2} [/tex]

[tex]x = 2 \sqrt{7} [/tex]

[tex]x = y = 2 \sqrt{7} [/tex]

Answer:

[tex]V=81\ \text{feet}^3[/tex]

Step-by-step explanation:

A wooden box has a square base

One side of the base is 3 feet

The height of this box is 3 times the length of one side of the base, h = 3(3) = 9 feet.

The volume of the box is given by :

[tex]V=A\times h[/tex]

A is area of base

For square base, A = side²

[tex]V=3^2\times 9\\\\=81\ \text{feet}^3[/tex]

So, the volume of this box is [tex]81\ \text{feet}^3[/tex]

Answer:

Step-by-step explanation:

For the problem:

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:

1

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

7 × 2

2 × 1

=  

14

2

The Greatest Common Factor (GCF) of 14 and 2 is 2. The result can be simplified by dividing both the numerator and denominator by 2.

==================================================

Explanation:

Apply the law of cosines to find angle C

c^2 = a^2 + b^2 - 2*a*b*cos(C)

19^2 = 11^2 + 17^2 - 2*11*17*cos(C)

361 = 121 + 289 - 374*cos(C)

361 = 410 - 374*cos(C)

361 - 410 = -374*cos(C)

-49  = -374*cos(C)

-374*cos(C) = -49

cos(C) = (-49)/(-374)

cos(C) = 0.131016042780749  ..... which is approximate

C = arccos(0.131016042780749)

C = 82.4716905247836

C = 82 degrees

Notes:

Answer:

House coordinate = (5, 1)

Library coordinate = (10, 13)

Step-by-step explanation:

Given :

House coordinate = (5, 1)

Library coordinate = (10, 13)

Distance between house snd library :

Distance = sqrt[(x2 - x1)² + (y2 - y1)]

x1 = 5, x2 = 10, y1 = 1, y2 = 13

Distance = sqrt[(10 - 5)² + (13 - 1)²]

Distance = sqrt[(5² + 12²)]

Distance = sqrt(25 +144)

Distance = sqrt(169)

Distance = 13

Answer:

w=5   x=2.1    y=5.4   z= 14.1

Step-by-step explanation:

w² = 13² - 12² = 25

w = 5

cos ∠1 = 12/13 = 13/(12+x)

12 (12+x) = 13 x 13 = 169

144 + 12x = 169

12x = 25

x = 25/12 = 2.08 = 2.1

∠1 + ∠2 = 90°

∠2 + ∠4= 90°    ∠4 = ∠1

sin ∠4 = x/y = sin ∠1 = 5/13

5y = 13x

y = 13/5 x = 13/5 * 25/12 = 65/12 = 5.4

z = 12 + x = 12 + 2.08 = 14.08 = 14.1

Answer:

Graph B

Step-by-step explanation:

Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y.

In this exercise we have to identify the treated inverse function and the graph that corresponds to it, so we have that what corresponds to this is:

Graph B corresponds to the given function.

In this way, the inverse function corresponding to:

[tex]f^{-1}(x)[/tex]

Because th inverse fuction is f^-1(x), you basicaly swap the numbers, all x valuese would equal y. So we will have that the graph that correctly corresponds to this function is graph B.
