Answer:

22.5

Step-by-step explanation:

Well, we know that a triangle's angles add up to 180°, so 45 + 35 + x = 180, and x = 100.

The third angle is 100.

Answer:

The measurement of the third angle is 100 degrees.

Step-by-step explanation:

Just add 45 + 35 which equals to 80. Every triangle's angles equal to 180 degrees so subtract 80 from 180. That equals 100 degrees.

Equation: 45+35=80

180-80=100

Answer:

The first one (highlighted one)

Step-by-step explanation:

The answer is the one selected. When multiplying and subtracting numbers, you do the combination that is multiplying before you subtract-unless there are numbers in parenthese. You work parentheses first. In all of the other options, you are multiplying first so not subtracting from 3. For example  the second option, you would multiply 4x7 BEFORE you subtract from 3 which doesn’t work. You are also multiplying first in options 3 and 4.

Step-by-step explanation:

The median of 5, 6, 3, 9, 0, 4, 1, 2, 7 is 4

We have:

5, 6, 3, 9, 0, 4, 1, 2, 7

Rearrange the dataset in ascending order

0, 1, 2, 3, 4, 5, 6, 7, 9

The median is the middle value, and the middle value in the above dataset is 4

Hence, the median of 5, 6, 3, 9, 0, 4, 1, 2, 7 is 4

Step-by-step explanation:

Since EC is 180,

180-30=150

Answer:

The missing angle is 24 degrees

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

x+156 = 180

Subtract 156 from each side

x+156-156 = 180- 156

x = 24

The missing angle is 24 degrees

The answer is B

Answer:

1

Step-by-step explanation:

the gradient is a value that indicates how much the x value increases as the y value increases. It can be written as

rise/run

or

change in  y value/change in x value

or

(y1-y2)/(x1-x2), where we know two coordinates (x1,y1) and (x2,y2).

We have two coordinates (0,0) and (3,3)

Therefore,

x1 = 0, y1 = 0

x2 = 3, y2 = 3

If we plug these values into the formula, it is [tex]\frac{3-0}{3-0} = \frac{3}{3} = 1[/tex]

Answer:

[tex]w = 52[/tex]

Step-by-step explanation:

Given

See attachment for intersecting lines

Required

Find w

Using the horizontal line as a point of reference, the blank angle between w and 76 equals w.

This is so because it corresponds to angle w, at the bottom of the horizontal line.

So, to find w, we make use of:

[tex]w + w + 76 = 180[/tex] --- angle on a straight line

Collect like terms

[tex]w + w = -76 + 180[/tex]

[tex]2w = 104[/tex]

Solve for w

[tex]w = \frac{104}{2}[/tex]

[tex]w = 52[/tex]

Answer:

∠1 = 72°

Step-by-step explanation:

exterior ∠ = the sum of two opposite(remote) interior ∠s

∠1 = 37° + 35°

=> ∠1 = 72°

Answer:

72 degrees.

Step-by-step explanation:

Angle 1 is one of the triangle's exterior angles. The exterior angle theorem states that the measure of a triangle's exterior angle is equal to the sum of the opposite interior angles. Therefore, m<1 is equal to the sum of 35 and 37:

35+37=72

m<1 = 72 degrees

Answer:

92 is your answer

Step-by-step explanation:

we have

3x/4-1=x/2+7 side of square are equal

3x/4-x/2=7+1

(3x-2x)/4=8

x=8×4=32

length =3×32/4 -1=24-1=23

now

perimeter=4×length=4×23=92 units

Answer: The perimeter of the square is 92 units.

Step-by-step explanation:

All four sides of a square are equal. Set the given values 3/4x - 1 and 1/2x + 7 equal to one another. It should like this: 3/4x - 1 = 1/2x+7. The next step is solving for x. We get x = 32 as our answer. See the image of the work below if you are confused. :)  Next, plug in this answer to the original equations: 3/4x-1 and 1/2x+7.

3/4(32) - 1 = 23

1/2(32) + 7 = 23

After basic substitution, we will conclude that each side of the square is 23 units long. To find perimeter use the equation 4s (let s represent sides). 4(23) = 92 units. Hope this was helpful!

Answer:

2r

Step-by-step explanation:

You suppose that the radius of a larger circle = r

so diameter = r*2 = 2r

aint really sure tho

Answer:

2R

Step-by-step explanation:

The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
