Add the two angles together  then subtract 180 to find the third angle which equals 130 degrees so you have all your angles now you need the definitions for acute, obtuse, and right angle

right angle has a 90 degree angle so that cant be it

<span>an acute angle is less than 90 degrees so that is not it
</span>
obtuse angle is larger than 90 degrees so that must be the correct answer.. the correct answer is obtuse

What is the volume of the rectangular prism - i ready. 1/3 ft some of. The answers 1 1/9 feet3- 10 ft3 - 2/9 ft3 - 3 1/3 ft3
Kamila [148]

Answer:

3\frac{1}{3}\ ft^3

Step-by-step explanation:

A rectangular prism is a polyhedron with six rectangular faces. The volume of a prism is given by:

Volume = width * height * length

From the diagram, the rectangular prism is made up of cubes. Each cube is has a size of 1/3 ft by 1/3 ft.

The height of the prism is made up of 5 cubes. Height = 5 * 1/3 = 5/3 ft.

The length of the prism is made up of 3 cubes. length = 3 * 1/3 = 1 ft.

The width of the prism is made up of 2 cubes. Width = 2 * 1/3 = 2/3 ft.

The volume of the prism = width * height * length = 2/3 * 5/3 * 1 = 10/9 ft³ =  3\frac{1}{3}\ ft^3

X=29 and y=10

You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
