The older square-shaped floppy diskettes measured 5 inches on each side. What was the diagonal length of a diskette?

A. √ 50 in.
B. √ 55 in.
C. √ 51 in.
D. √ 58 in.

The diagonal length of a diskette is

Step-by-step explanation:

Given:

sides = 5 inches

To Find:

diagonal length of a diskette = ?

Solution:

The diskette is in the shape of square

So the diagonal of  square =

where  s is the side of the square

On substituting the square value

The diagonal of diskette =

The diagonal of diskette =                        

The diagonal of diskette =

step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
