Does anyone know this?

The rectangle's length is 30 inches while it's width is 24 inches.

Step-by-step explanation:

Step 1; Any rectangle's area is calculated by multiplying the rectangle's length and its width. Assume the the rectangle's length is 5x while it's width is 4x as it is given that the ratio of it's length to width is 5: 4.

Area of the rectangle = 5x × 4x = 720, 20x² = 720.

x² = = 36, x =√36 = 6.

Step 2; As we assumed length equals 5x and the width will equal 4x.

The rectangle's length = 5x = 5 × 6 = 30 inches,

The rectangle's width = 4x = 4 × 6 = 24 inches.

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.
