Answer:

67.9

Step-by-step explanation:

The polygon has 6 sides.

Sum if interior angles = (n-2)180

=(6-2)180

= 4 x 180

= 720

A + B + C + D + E + F = 720

x+40 + 2x-9 + 2x + 2x + x + x+78 = 720

9x + 109 = 720

9x = 720-109

9x = 611

x = 611/9

x = 67.9

Answers

Y - 3 = X + 2 ...............….... (1)
2X - 1 = Y ........................... (2)

From (2),
2X - 1 = Y

Y = 2X - 1


Sub (2) into (1),
(2X-1) - 3 = X + 2

2X - 1 - 3 = X + 2

2X - X = 2 + 1 + 3

X = 6

A plot of land is 25 feet in length and 20 feet wide, and it is in the shape of a parallelogram. The perpendicular distance from the long side to the opposite long side is 18 feet. What is the area of the piece of land?

Answers

Given:

Length of the parallelogram = 25 feet

Width of the parallelogram = 20 feet

Perpendicular distance from the long side to the opposite long side = 18 feet.

To find:

The area of the piece of land which is a parallelogram.

Solution:

Area of a parallelogram:

[tex]Area=Base\times height[/tex]

Let the longer side, 25 feet is the base, then the height of the parallelogram is 18 feet. So, the area of the parallelogram is

[tex]Area=25\times 18[/tex]

[tex]Area=450[/tex]

Therefore, the area of the piece of land is 450 square feet.

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 3672 no votes what was the total number of votes

Answers

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes

Find the value of x. in the below given diagram.

Answers

Answer:5,8

Step-by-step explanation:

x^2= 3^2 + 5^2

x^2= 9 + 25

x^2= 34

x = (square root)34

x= 5,8

Answer:

x = [tex]\sqrt{34}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )

x = [tex]\sqrt{34}[/tex] ← exact value

x ≈ 5.83 ( to 2 dec. places )
