Find the measure of an interior angle of a regular nonagon (9-sided polygon).
Scrat [10]

The measure of an interior angle of a regular nonagon (9-sided polygon) is 140°

<h3>How to determine the angle</h3>

The formula for sum of interior angles of a polygon is given as;

= ( n -2) × 180

Recall that a nonagon has nine sides, so , n = 9

Substitute the value into the formula

= ( 9 -2) × 180

= 7× 180

= 1260°

Since the sum of the angles =  1260°

One of the angles = 1260/ 9 = 140°

Therefore, the measure of an interior angle of a regular nonagon (9-sided polygon) is 140°

The ratio of the price of two goods on a graphed budget line is measured by its.
UkoKoshka [18]

In Mathematics, the ratio of the price of two (2) goods that is represented on a graphed budget line is measured by its: slope.

<h3>What is a graph?</h3>

A graph is a statistical tool that is primarily used for the graphical representation of data by using both the horizontal and vertical lines, which are denoted as x-axis and y-axis respectively.

<h3>What is slope?</h3>

The slope of a line can be defined as the gradient of a line and it's typically used to describe both the ratio, direction and steepness of an equation of a straight line.

Mathematically, the slope of a line is given by the following formula;

Slope, \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope, \;m = \frac{y_2 - y_1}{x_2 - x_1}

In conclusion, the ratio of the price of two (2) goods that is represented on a graphed budget line is measured by its slope.

Can someone answer this?
Harman [31]

Answer:

Length of mammoth's tusk in  poster = 15.33

Step-by-step explanation:

Actual height of mammoth = 10 feet 5 inches = 126 inches

Height on the poster of mammoth = 14 inches

Actual length of mammoth's tusk = 11.5 feet = 138 inches

Length of mammoth's tusk in  poster = x

126 : 14  :: 138  : x

Product of mean = product of extremes

x * 126 = 14 * 138

x = \frac{14*138}{126}

x = 15.33
