Answer:

let ratios be x

2x +3x+4x=180(Sum of triangles)

x=20`

2X=20

x=20×2

X=40

3x=20

X=60

4x=20

x=80

largest angle is 80

Step-by-step explanation:

plz make me brainliest

Answer:

80°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the parts of the ratio, 2 + 3 + 4 = 9 parts

Divide 180° by 9 to find the value of one part of the ratio

180° ÷ 9 = 20° ← value of 1 part of ratio, then

2 parts = 2 × 20° = 40°

3 parts = 3 × 20° = 60°

4 parts = 4 × 20° = 80°

The measure of the largest angle is 80°

Answer: 24, 10, 68, 17

Step-by-step explanation:

Answer:

because they are congruent to the original angle

Step-by-step explanation:

they are congruent to the original triangle. nothing will change.

The two perpendicular lines will remain perpendicular because it should be congruent to the original angle.

The Two geometric figures should treated be congruent in the case when it should have coincided. Since the both perpendicular lines are dilated by the same factor also the same center should be used due to this, the two perpendicular lines should remain perpendicular.

Therefore, The two perpendicular lines will remain perpendicular because it should be congruent to the original angle.

Answer: 5 gallons per hour.

Step-by-step explanation: To find the unit rate, divide "gallons" by "hours." As we said, we need to find the unit rate. We want a unit rate where 1 is in denominator, so we divide the top and bottom by 6. (Remember, unit means 1.)

[tex]\frac{30/6}{6/6}=\frac{5}{1}[/tex]

Therefore, our answer is 5.

Answer:

yes it is

Step-by-step explanation:

Answer:

It is, because it is equal to 5.

Step-by-step explanation:

To convert from gallons to quarts, multiply the gallon value by the conversion factor. For example, if converting from US fluid gallon to US fluid quart, then multiply the gallon value by 4. For example, to find out how many quarts in a half gallon of water, multiply 4 by 0.5, that makes 2 quarts in a half gallon.

lolll i love those games rn im playing one abt a lil guy on a bike

Answer:

Eudora spent 0.5 hours from home to library and 1.5 hours from library to school

Step-by-step explanation:

Given

Home to Library:

[tex]S_1 = 12km/h[/tex] -- Average Speed

Library to School

[tex]S_2 = 76km/h[/tex] -- Average Speed

Total

[tex]Distance = 120km[/tex]

[tex]Time = 2\ hr[/tex]

Required

Determine the time taken from home to library and from library to school

Let the time spent from home to library  be x. So, from library to school will be: 2 - x

So, we have:

Home to Library:

[tex]S_1 = 12km/h[/tex] -- Average Speed

[tex]T_1 =x[/tex] -- Time

Library to School

[tex]S_2 = 76km/h[/tex] -- Average Speed

[tex]T_2 =2 - x[/tex] -- Time

Distance is calculated as:

[tex]Distance = Speed * Time[/tex]

Home to Library:

[tex]D_1 = S_1 * T_1[/tex]

[tex]D_1 = 12 * x[/tex]

[tex]D_1 = 12x[/tex]

Library to School:

[tex]D_2 = S_2 * T_2[/tex]

[tex]D_2 = 76 * (2- x)[/tex]

[tex]D_2 = 152- 76x[/tex]

The total distance is 120km. So, we have:

[tex]120km = D_1 + D_2[/tex]

[tex]120 = 12x + 152 - 76x[/tex]

Collect Like Terms

[tex]120 - 152 = 12x - 76x[/tex]

[tex]-32 = -64x[/tex]

[tex]-64x=-32[/tex]

Solve for x

[tex]x = \frac{-32}{-64}[/tex]

[tex]x = 0.5[/tex]

Recall that:

[tex]T_1 =x[/tex]

[tex]T_2 = 2 - x[/tex]

So, we have:

[tex]T_1 = 0.5[/tex]

[tex]T_2 = 2 -0.5 = 1.5[/tex]

Answer:

25

Step-by-step explanation:

Let n be the first integer.

Then the second integer will be (n + 1).

And the third will be (n + 2).

The sum is 78. Therefore:

[tex]n+(n+1)+(n+2)+78[/tex]

Solve for n. Combine like terms:

[tex]3n+3=78[/tex]

So:

[tex]3n=75[/tex]

Therefore:

[tex]n=25[/tex]

Therefore, the first integer is 25.

So our sequene is 25, 26, and 27.

The integer closest to zero will thus be 25.

Vertical Angles

Step-by-step

I believe this is the case because since the angles intercept in order to form also it's the only answer that has to do with intercepting from what we can see from the diagram.

There are different types of relationships between angles including alternate, corresponding, vertical, adjacent, complementary and supplementary angles

The correct option for the relationship that best describes angles AFC and DFB is option D;

D) Vertical angles

The reason the chosen option is correct is as follows;

The given diagram shows line EF perpendicular to line AB and line CD crosses line AB at point F

Therefore, the angles ∠AFC and ∠DFB formed by lines AB and CD with their orientation in the order of their names are opposite to each other and other are known as vertical angles
