Answer:

x= 17

Step-by-step explanation:

Assuming that the total degree of this side is also 90, we'll subtract 90 with 39.

90 - 39= 51

since x is 3 times the total degree, we'll divide 51 by 3, leaving us with 17.

So the total line equals 180 degrees, and the that a little square is 90 degrees. And 180 - 90 = 90. So now we now that both sides are 90 degrees. And for the right side we know that half of it is 39 degrees, and we need to find the other or x. So we do 90 - 39 which is 51, and now we have to figure out what multiplied by 3 gives 51. So it's like 3 × _ = 51. And that blank is 17, and you get that when you divide 51 by 3. X = 17

Find the length of the altitude to the hypotenuse. Round the answer to the nearest tenth, if needed.

To solve this, it might be easier to draw it out (see the picture below). I split it into two triangles and used trig functions to find the altitude. I used the big triangle to find theta, and the used theta to find the side of the altitude. *remember that sine= opposite/hypotenuse*

<em>We will assume the tent is in the shape of a triangular prism.</em>

The volume of a triangular prism can be found with the following formula, where $b$ is the width at the base, $h$ is the height, and $l$ is the length.

$V=\frac{1}{2}bhl$

Substitute in the known values.

$V=\frac{1}{2}*5*3*8$

Simplify — use multiplication.

$V=\frac{5}{2}*3*8$

$V=\frac{15}{2}*8$

$V=\frac{120}{2}$

Simplify — use division.

$V=\large{\boxed{60\ \text{ft}^{3}}}$

The volume — or in this case, the amount of living space — is $60\ \text{cubic feet}$ .

As part of a survey, 150 students were asked to name their favorite class. 50 points

A:40%
If you put 60 over 150 and x(percent of students) over 100 and cross multiply 100 and 60, you will get 6000. You then divide that by 150 which leaves you with 40 as x and 40 over 100 is 40%.
