What is the measure of an exterior angle of a regular pentagon?


a.
108°

b.
72°

c.
80°

d.
58°

Answer:

Coordinates involve two points. (x,y)

Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.

For example

Point A is number 1 on the y axis

number -4 on the x axis

So, you would write the coordinate out at

(-4,1)

The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.

The equation will be 63=9*n.

We have to first start with what is given,

The given statement is Sixty-three is the product of nine and a number, an equation generally contains both some constants and variables. Here in the given question we have to identify the constants and the variables, the constant as we can see is Sixty three and the number with which we have a product is also a constant that is nine.

Now the unknown variable is the one with which nine is multiplied, generally in mathematics we represent unknown by n so hence the final equation becomes 63 = 9*n.

Answer:

Line B

Step-by-step explanation:

We can solve this by finding the y-intercept

In the equation y=x+3, 3 is the y-intercept

And if we look at the graph we can see that the line that intersects with 3 is line B.

37 : 5 = 7,4

so 7 sets + [37 - (7x5)] = 2 left over

7 x 5 + 2 = 37

Answer:

The correct answer is C. 7 sets with 2 left over

Step-by-step explanation:

7 × 5 = 35

37 - 35 = 2

Answer:

z=7 and x=60

Step-by-step explanation:

well from the square that is combining the angles 1 and 2, they tell you that that is a right angle and you know that angle 2 is 38 so 90-38=52 which is the measurement of angle 1 so to find z, you would have to divide 38/-2 which is -19 and then add 12 so 12-19=-7 so z=7. so you know that one side =90 degrees so angle 3 must also =90 degrees because they are on the same line and a line is equal to 180, so all you have to do is reverse the operations in 1 1/2x to find x, so 1 1/2 or 3/2 divided by 90 is 60.

Answer:

18

Step-by-step explanation:

Since 3 is positive, the inequality direction remains the same. Divide both sides by 3. Since 3 is positive, the inequality direction remains the same Divide 54 by 3 to get 18

Answer:

185.8-(25+1)*3

185.8-26*3

answer: 107.8

Answer:

We know what all of these signs mean, but what does 5^2 mean? I'll show you.

5^2, more commonly known as 5 squared, means a number times itself.

With that given info, we can multiply 5 times itself and find the answer.

[tex]5 * 5 = 25[/tex]

Put 25 in the blank.

Now you know what to do.

Answer:

12in

Step-by-step explanation:

15in squared - 9in squared is 144in and the square root of 144 is 12

Answer:

12 in

Step-by-step explanation:

Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

let x = unknown side

Given:

Substituting the given values into the equation:

⇒ x² + 9² = 15²

⇒ x² + 81 = 225

⇒ x² + 81 - 81 = 225 - 81

⇒ x² = 144

⇒ x = √(144)

⇒ x = ±12

As the length is positive, x = 12 only.

Therefore, the length of the unknown side is 12 in.

Answer:

They would be 5%

Step-by-step explanation not for sure but what I did was add the correct numbers and added the incorrect numbers and It came out to 110 and 105 so I used 110/105 and looked at how much the percentage was and then when I got that I just took the percentage that would make it 100 percent. Hope it helps and sorry if it is incorrect I tried.

Answer:

9 multiply 3 = 21

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

both lunes c and d are parrallel

line c =

∠1 + ∠4 = 240°

360 -240= 120 °

120/2 = 60°

as angle 2 and 3 are opposite each other they will have the same angle { 60°}

line d =

∠5 is 120° , ∠5 and ∠8 are opposites so ∠8 is equal to 120°

120 ×2 = 240

360-240=120°

120° / 2 = 60°

so ∠7 and ∠6 are 60°

both lines are parallel as the angles are corresponding

Answer:

x = 3

Step-by-step explanation:

4x+2 = x+11

Subtract x from each side

4x+2-x = x+11-x

3x+2 =11

Subtract 2 from each side

3x+2-2 =11-2

3x = 9

Divide by 3

3x/3 =9/3

x = 3

Answer:

x=3

Step-by-step explanation:

4x + 2 = x + 11

subtract 2 and x from both sides

3x = 9

divide by 3 on both sides

x = 3

Step-by-step explanation:

(2x - 3) + 8x = 180 (linear pairs)

10x - 3 = 180

10x = 180 + 3

10x = 183

x = 183÷10

x = 18.3

1 = 2x - 3

2 × 18.3 - 3

= 33.6

2 = 8x

8 × 18.3

146.4

Angle 1 + Angle 2 = 180

33.6. + 146.4. = 180

Answer:

32, 52, 96

Step-by-step explanation:

add all the angles together

x + (2x - 12) + 3x

= 6x - 12

all angles in a triangle add to 180 so

6x - 12 = 180

add twelve on both sides to get rid of it

6x = 192

divide both sides by 6x

x = 32

now substitute

x = 32

2x - 12 = (32 x 2) - 12 = 52

3x = 32 x 3 = 96

okay so the total degrees of this graph 90° because it's a right angle. so I'm pretty sure you would subtract 4x from 90.

4x-90=x

add like terms( there is an understoon 1 when a variable is by itself) :

90=5x

divide 90 by 5:
