Step-by-step explanation:

Step-by-step explanation:

a) m∠AOB = 360°/8 = 45°

Internal angle is 360°, divided by 8 sides of octagon

b) m∠ABC = 2m∠ABO

m∠ABO = m∠BAO = 1/2(180° - 45) = 1.2(135°)

m∠ABC = 2*1/2(135°) = 135°

Answer:

a) 45

b)135

Step-by-step explanation:

[tex]In\ order\ to\ find\ the\ sum\ of\ all\ the\ interior\ angles\ of\ a\ polygon\ with\ sides\ n,\\S=180(n-2)\\Here,\\As\ the\ figure\ is\ a\ regular\ octagon\ ,\\The\ sum\ of\ all\ of\ its\ angles\ = 180(8-2)\\=180*6=1080\\Hence,\\Given\ that\ it\ is\ regular\ or\ that\ all\ of\ its\ angles\ are\ equal\ in\ measure.\\Hence,\\b) Angle\ ABC=1080/8\\=135\\As\ it\ is\ regular\ , the\ diagonals\ passing\ through\ the\ center\ bisects\ the\ respective\ angles.[/tex]Hence,

[tex]Angle OAB=135/2 = 67.5\\Angle ABO=135/2=67.5\\Through\ the\ angle\ sum\ property\ of\ a\ triangle\\Angle OAB+AngleABO+Angle AOB=180\\67.5+67.5+AngleAOB=180\\135+AngleAOB=180\\Angle AOB=180-135\\=45[/tex]

Answer:

x = 12

Step-by-step explanation:

In a pair of intersecting lines the vertically opposite angles are equal.

[tex] \longrightarrow [/tex] (6x + 7)° = (8x - 17)°

[tex] \longrightarrow [/tex] 6x + 7 = 8x - 17

Subtract 8x + 7 from both sides:

[tex] \longrightarrow [/tex] 6x + 7 - (8x + 7) = 8x - 17 - (8x + 7)

[tex] \longrightarrow [/tex] (6x - 8x) + (7 - 7) = (8x - 8x) + (-17 - 7)

6x - 8x = -2x:

[tex] \longrightarrow [/tex] -2x + (7 - 7) = (8x - 8x) + (-17 - 7)

7 - 7 = 0:

[tex] \longrightarrow [/tex] -2x = (8x - 8x) + (-17 - 7)

8x - 8x = 0:

[tex] \longrightarrow [/tex] -2x = -17 - 7

-17 - 7 = -24:

[tex] \longrightarrow [/tex] -2x = -24

Divide both sides by -2:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{-2x}{-2} = \dfrac{-24}{-2} [/tex]

[tex] \sf \dfrac{-2}{-2} = 1 [/tex]

[tex] \longrightarrow [/tex] [tex] \sf x = \dfrac{-24}{-2} [/tex]

[tex] \sf \dfrac{-24}{-2} = 12 [/tex]

[tex] \longrightarrow [/tex] x = 12

Answer:

first term is 6

Step-by-step explanation:

MULTIPLY BY 4

1) 6  (1st term)

2)     6x4 = 24    (24 is the second)

3)    24 x 4 = 96 (96 is the 3rd)

4) 96 x 4 = 384 (384 the 4th)

Answer:

x = 4 and y = 0

Step-by-step explanation:

Using the elimination method:

4(-x + 5y=-4) --> -4x + 20y = -16.

Now we add -4x + 20y = 016 and 4x + 3y = 16. This gives us 23y = 0 or just y =0.

Now we can find x by plugging in y.

-4x + 0 = -16.

Divide by -4 on both sides -> x = 4.

If you want to double check you can plug your values into -4x + 20y = -16.

-4(4) +20(0) = -16.

Answer:

Option C

Step-by-step explanation:

Since it's draining, it means it must start at a certain value and end at a maximum of 0 since water cannot ever be less than 0. Since it's original amount is 40, it can only start draining from 40 and end at max 0 hence 0 ≤ y ≤ 40

Answer:

-6x - 8y - x² - 9y² - x - 6² - x² - y² - y = - 2x² - 10y² - 7x - 9y - 6²

Answer:

-9?

Step-by-step explanation:

Answer:

it would be an acute angle because it is less than 90

Answer:

It would be a right triangle

Step-by-step explanation:

A triangle must always have 3 angles that add up to 180°.

So if two angles are 45°, then the last angle has to add along with the 45° angles to equal 180°.

If you multiply 45 × 2 (since there are two angles that are 45°), you get 90, which is half of 180.

Also a 90° angle is a right angle, which would help you out with remembering.

Answer:

It is only 3,9.

Step-by-step explanation:

You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:

2(9) = 7(3)-3

18= 18

The answer is (3,9).

Answer:

1) The measure of the third angle is 60°

2) The length of the opposite side to the angle 30° is 1 cm

3) The length of the opposite side to the third angle 60° is approximately 1.732 cm

Step-by-step explanation:

1) The given parameters are;

The known angle of a right triangle = 30°

The length of the hypotenuse = 2 cm

Given that the triangle = A right triangle, with one of the interior angles = 90°, we have;

The measure of the third angle = 180° - 90° - 30° = 60°

The measure of the third angle = 60°

2) We have that sin(30°) = 0.5 = (The length of the opposite side to the angle 30°)/(The length of the hypotenuse side)

0.5 = (The length of the opposite side to the angle 30°)/(2 cm)

∴ The length of the opposite side to the angle 30° = 2 cm × 0.5 = 1 cm

The length of the opposite side to the angle 30° = 1 cm

3) Similarly, the length of the opposite side to the third angle 60° = sin(60°) × (The length of the hypotenuse side)

∴ The length of the opposite side to the third angle 60° = (√3)/2 × 2 cm = √3 cm

The length of the opposite side to the third angle 60°  = √3 cm ≈ 1.732 cm

Answer: 3.75

Step-by-step explanation:

The following can be gotten from the question:

Time taken for each session = 4/5 hours

Total time set aside by principal = 3 hours

The number of sessions that can be sheduled for each student will be:

= Total time set aside by principal / time taken for each session

= 3 hours / 4/5 hours

= 3 × 5/4

= 3.75
