expeople1 [14]

Answer:

Step-by-step explanation:

The graph shows the prices, in dollars, of different numbers of pies at Erik's store. The table shows the prices, in dollars, of different numbers of doughnuts at the same store. A graph shows Number of Pies on x-axis and Price of Pies on y-axis. The x-axis scale is shown from 0 to 12 at increments of 2, and the y-axis scale is shown from 0 to 160 at increments of 20. A straight line joins the ordered pairs 2, 20 and 4, 40 and 6, 60 and 8, 80 and 10, 100 and 12, 120. Doughnuts Number of Doughnuts Price of Doughnuts (dollars) 2 6 4 12 6 18 8 24 How many dollars more is the price of a pie than the =doughnut at Erik's store? $2 $3 $6 $7The graph shows the prices, in dollars, of different numbers of pies at Erik's store.

Nezavi [6.7K]
The answer is 36

Multiply each side by 9

9 times for and 9 times n/9

The n/9 will cancel out so you are left with n= 9 times 4

This comes to 36

Angle. How many sides does the polygon have?
tia_tia [17]

The measures of the four angles of quadrilateral ABCD are 36°, 72°, 108° and 144°

<u>Explanation:</u>

A polygon has three or more sides.

Example:

Triangle has 3 sides

Square has 4 sides

Pentagon has 5 sides and so on.

27)

In a quadrilateral ABCD, the measure of ZA, ZB, ZC and ZD are the ratio 1 : 2 : 3 : 4

We know,

sum of all the interior angles of a quadrilateral is 360°

So,

x + 2x + 3x + 4x = 360°

10x = 360°

x = 36°

Thus, the measure of four angles would be:

x = 36°

2x = 2 X 36° = 72°

3x = 3 X 36° = 108°

4x = 4 X 36° = 144°

Therefore, the measures of the four angles of quadrilateral ABCD are 36°, 72°, 108° and 144°
