Question: 1 / 225

Nominally vertical means an angle not more than how many degrees of the vertical?

30 degrees

45 degrees

"Nominally vertical" refers to an angle that is very close to being perfectly vertical, but not exactly. This means that the angle is not more than 45 degrees away from the exact vertical. Options A and C are incorrect because they exceed the 45 degree limit. Option D, 90 degrees, is also incorrect because it is the exact vertical and not within the specified range.

60 degrees

90 degrees
