The human eye can sharply see objects within a 15 Dagrees horizontal angle either side of the direction of focus. Arlo is design
faltersainse [42]

Answer:

Maximum width of image that can be viewed clearly on the cylindrical screen is 10 ft

Step-by-step explanation:

Here we have

Circumference of screen = 2πr = 120 ft

Angle that can be viewed horizontally either side of focus = 15°

Total angle view = 30°

Size of image that can be viewed = Object within 30° of focus

Maximum width of image that can be viewed clearly = Perimeter of 30° arc section of cylinder

Maximum width of image that can be viewed clearly = 30/360×120 ft = 10 ft.

Maximum width of image that can be viewed clearly on the cylindrical screen = 10 ft.

Write the measure -128 30’ 45’’ as a decimal to the nearest thousandth
Zielflug [23.3K]

Answer:

-127.488°

Step-by-step explanation:

45" is 0.75 of 1', so -128° 30' 45" = -128° 30.75'

Next:  30.75' is 30.75/60 of 1°, and or -128° plus 0.5125 of 1°.

The final answer is found by adding 0.5125° to -128°:

 -128.0000°

 +   0.5125°

--------------------

 -127.4875

To the nearest thousandths of a degree, that would be -127.488°
