Answer:

x = 16.6

Step-by-step explanation:

Since we know the measure of an acute angle (31 degrees) of a right angle triangle, and of the side opposite to the angle (10), and we need to find the measure of the adjacent side "x", we use the tangent function:

tan(\theta) = \frac{opposite}{adjacent} \\tan(31^o)=\frac{10}{x}\\x=\frac{10}{tan(31^o)} \\x \approx 16.64279

which rounded to one decimal is

x = 16.6

The other leg is 12cm long.

Step-by-step explanation:

Given,

Hypotenuse = c = 15cm

One leg = a = 9cm

Other leg = b

As the triangle is right angled, therefore, using Pythagoras theorem;

a^2+b^2=c^2\\(9)^2+b^2=(15)^2\\81+b^2=225\\b^2=225-81\\b^2=144\\

Taking square root on both sides;

\sqrt{b^2} =\sqrt{144} \\b=12\ cm

The other leg is 12cm long.

Keywords: triangle, square root

Slope of a line represents the money billed per lesson length.

Step-by-step explanation:

Slope of a line defined as the the number that measures the steepness and it is usually denoted by m.

It is also states the gradient of a line or the change in variable of y to the change in variable of x.

As per the statement:

Slope of a line is 2/3.

Here x axis represents the lesson length in minute and y axis represents the money billed in dollars

Then;

Slope of a line represents the money billed per lesson length.
