Answer:

x = 18√3

Step-by-step explanation:

From the picture attached,

In a right triangle,

Measure of one angle = 30°

Measure of adjacent side of the angle = 9 units

We have to find the measure of Hypotenuse from the given properties.

By cosine rule,

cos(30°) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

\frac{\sqrt{3}}{2} =\frac{9}{x}

x=18\sqrt{3}

Therefore, measure of Hypotenuse is 18√3 units.

After driving 10 miles, in a 1/3 of a day, Mark is trying to figure out how many
svet-max [94.6K]

Answer:

30 miles

Step-by-step explanation:

Let the number of days = d

in 1/3 of a day, or 1/3d, he drove 10 miles

The equation is:

10 = \frac13d

To find out the number of miles driven in one whole day, we can multiply both sides by 3 or setting up a proportion

<h2>Method 1: Multiplying By 3</h2>

10 = 1/3d

10*3 = 1/3d * 3

30 = 1d

30 miles

<h2>Method 2: Proportions</h2>

\frac{10}{1} = \frac13

10*3 = 1*1                 Cross multiply

30 = 1
