What angle pair is pictured?


1)Alternate lantern angles
2)corresponding angles
3)same-side interior angles
4)Alternate exterior angles

Answer:

If Angle A and Angle B are vertical angles,

what is value of x?

D. 8

If Angle A and Angle B are supplementary

angles, what is measure of

Angle B?

D. 140

Step-by-step explanation:

If Angle A and Angle B are vertical angles,

what is value of x?

Vertical angles are congruent thus

40° = 5x°

5x° = 40°

(5x / 5)° = (40 / 5)°

x° = 8°

If Angle A and Angle B are supplementary

angles, what is measure of

Angle B?

Supplementary angles add up to 180° or a straight line.

180° – 40° = 140°

Slope is change in y over change in x:

Slope = (5c - 3c) / ( 2c -c)

Slope = 2c/c = 2

The answer is D. 2

Answer:

107 degrees

Step-by-step explanation:

All polygon degrees add up to 360

we know that this polygon has a angle of 90 and 56

subtract 90 and 56 from 360 to get 214

Then divide by 2 because there are 2 x angles

to get 107 degrees

Answer:

3072ft

Step-by-step explanation:

we have,

h(t)=-16t²+192t+2560

where

h -----> is the height in feet of the rock

t -----> the time in seconds

For t=8 seconds

substitute the value of t in the function and find the value of h

h(8)=-16(8)²+192(8)+2560

=3072ft

Answer:

1.

centre(h,k)=(-13,9)

radius (r)=6

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x+13)²+(y-9)²=6²

(x+13)²+(y-9)²=36you can write this equation too

x²+26x+169+y²-18y+81=36

x²+y²+26x-18y +214=0

is a required equation of the circle.

2.

centre(h,k)=(1,-1)

radius (r)=11

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x-1)²+(y+1)²=11²

(x-1)²+(y+1)²=121

is a required equation of the circle.

3.

centre (h,k)=(3,1)

radius (r)=4units.

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x-3)²+(y-1)²=16 is a required equation.

4.

centre(h,k)=(4,-2)

radius (r)=3

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x-4)²+(y+2)²=3²

(x-4)²+(y+2)²=9

you can write this equation too

Step-by-step explanation:

Answer:

a) Thin mints = 1.885 radians

b) Savannah smiles cookies = 0.332 radians

Step-by-step explanation:

To convert an angle from degree to radians, the formula is given as :

x ° × π/180 = radians

Where x = angle to be converted

From the diagram we are to convert Thin mints and Savannah cookies to radians

a) Thin mints = 108°

Converting to radians

= 108° × π/180

= 1.8849555922 radians

Approximately = 1.885 radians

b) Savannah smiles cookies = 19°

Converting to radians

= 19° × π/180

= 0.331613 radians

Approximately = 0.332 radians

Answer:

16 Hours

Step-by-step explanation:

25 x 20 x 4 = 2000ft cubed.

2000ft divided by 125ft cubed = 16

Answer:

-5

Step-by-step explanation:

Given the functions

f(x) = 2x - 20

g(x) = x - 1

f(x)/g(x) = 2x - 20/x-1

f/g(x) = 2x - 20/x-1

Substituting x = -5 int the result

f/g(5) = 2(5) - 20/5-1

f/g(5) = 10 - 20/4

f/g(5) = -10/4

f/g(5) = -5

Hence the result is -5

Step-by-step explanation:

Answer:

3/10. 0.3

Step-by-step explanation:

when you divide mixed numbers you should reciprocate them I mean take the reciprocal and that was 2 and over every number there is one so I took 1/2 hope you understand why I kept 1/2 I took its reciprocal hope you understand if I'm wrong tell me right away I'll try it out good luck.

Answer:

To find the surface area of a cone, you need to calculate the cone’s base and the lateral surface area.

Since the base of a cone is a circle, then the base area (B) of a cone is given as:

Base area of a cone, B = πr²

Where r = the base radius of the cone

Step by Step Explanation:

A=πr²

Answer:

x = - 1 ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

To solve the equation let y = 0 , that is

x² + 2x - 6 = 0 ( add 6 to both sides )

x² + 2x = 6

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = 6 + 1

(x + 1)² = 7 ( take the square root of both sides )

x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )

x = - 1 ± [tex]\sqrt{7}[/tex]
