solve for a, geometry work

Answers

Answer 1

Answer:

a = 45 degrees

Step-by-step explanation:

Since both angles are a, they are equal to each other

Also, we know that the right angle means it measures 90 degrees

So, (180-90)/2 = a

a = 45 degrees

Answer 2

Sum of interior angles in a triangle =180
a+a+90=180
2a+90=180
2a=180-90
2a=90
a=90/2
a=45

The net of a cube is shown below. If the surface area of the net is 294 in^2 , then what is the length of each side of the cube?

Answers

Answer:

7 in

Step-by-step explanation:

294:6=49

[tex]\sqrt{49}=7 in[/tex]

The length of each side of the cube is 7 inches.

What is surface area of a cube?

The surface area of the cube all six faces of the cube are made up of squares of the same dimensions then the total surface area of the cube will be the surface area of one face added six times to itself. The formula to find the surface area of a cube is 6a², where a is edge.

Given that, the surface area of a cube is 294 square inches.

Now, 6a²=294

a²=294/6

a²=49

a=7 inches

Therefore, the length of each side of the cube is 7 inches.
