Volume is the measure of how much space a 3d object takes up (like area for 2d objects). It is measured in cubic parts (5 cubic inches, 12 cubic centimeters). There are many volume formulas. The easiest and most common is of the volume of a rectangular prism, for which you do lenght * width * height..

I hope this answers your question!

Volume is how much a 3D object takes up space and it can be measured by length times width and multiplied by height

Find the area of △ABC with side lengths b = 6 and c = 17, and included angle A = 135∘. Round your answer to the nearest tenth

Cloud [144]

Answer:

<u>Area = 36.1 sq. units</u>

Step-by-step explanation:

We will use the "included angle area" formula for a triangle to solve this problem.

The formula is:

$A=\frac{1}{2}abSinC$

Where

a and b are the two sides given

C is the angle given BETWEEN the two sides

From the problem, we can write:

the two sides are 6 & 17, so that will be "a" and "b" of the formula

the included angle is 135, so that will be "C" of the formula

Substituting, we find the answer:

$A=\frac{1}{2}abSinC\\A=\frac{1}{2}(6)(17)Sin(135)\\A=36.06$

Rounded to 1 decimal place,

<u>Area = 36.1 sq. units</u>

J has coordinates of (10,-2) and N has coordinates of (-4,6) find the midpoint of JN

faltersainse [42]

To find the midpoint, you are basically finding the average (or mean) between the two coordinates, J and N.

Start by finding the average between the x coordinates of J and N: 10 and -4. Add them together then divide the total by 2.

10 + (-4) = 6; 6/2 = 3

The average of the x coordinates is 3. Now find the average of the y coordinates. Start by adding -2 and 6 together then dividing the total by 2.

-2 + 6 = 4; 4/2 = 2

3 is the average of the x coordinates and 2 is the average of the y coordinates, so that means the midpoint of J and N must be (3, 2).
