Given angle a, how can you construct an angle whose measure is one fourth m angle a?
a. construct the angle bisector of angle a, and then construct the bisector of one of the newly created angles.
b. construct the angle bisector of angle a, then construct an angle that is congruent to one of the newly created angles.
c. construct the angle bisector of angle a, then construct the perpendicular bisector of the angle bisector.
d. construct the angle bisector of angle a, then construct a segment that is congruent to the angle bisector.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
