The measure of five is 5.
The measure of five is 5.
To find the measure of angle 5, we can use the relationship between the arcs and the angles they subtend. If angle 5 subtends arc BC, then the measure of angle 5 is half the measure of arc BC. Therefore, angle 5 would measure ( \frac{42}{2} = 21 ) degrees. If angle 5 relates to arc DE, further information is needed to determine its measure.
No, arc measure is an ambiguous expression since it could also refer to the angular measure of the arc.

The measure of an arc is part of the circumference of a circle
Arc measure is the number of radians. Two similar arcs could have the same arc measure. Arc length is particular to the individual arc. One must consider the radius of the arc in question then multiply the arc measure (in radians) times the radius to get the length.
To find the measure of a major arc in a circle, first determine the measure of the corresponding minor arc, which is the smaller arc connecting the same two endpoints. The measure of the major arc is then calculated by subtracting the measure of the minor arc from 360 degrees. For example, if the minor arc measures 120 degrees, the major arc would measure 360 - 120 = 240 degrees.

major arc
the measure of a minor arc equals the measure of the central angle that intercepts it.
