option:-d)#angle6#

Explanation:

Supplementary angle:-
#=># When the sum of two angles are #180^@#, then one angle is other's supplementary angle.

Here,the sum of #angle5# and #angle6# is #180^@# ,hence #angle5# and #angle6# is supplementary to each other.

Hope it helps..
Thank you...

#/_6# is supplementary to #/_5#

Explanation:

Supplementary angles are angles that add up to 180 degrees. Let's go through each of the answer choices:

#/_1#: Angles 1 and 5 are acute angles, thus they cannot add up to 180.

  • The largest value an acute angle can take on is 89 degrees. #89+89= 178#. This rules out angle 1.

#/_2#: Angle 2 is an acute angle, and so is angle 5. The highest measure an acute angle can take on is 89 degrees.

  • #89+89= 178#, which is just short of 180 degrees, so #/_2# is not supplementary to #/_5#.

#/_4#: Again, angles 4 and 5 are two acute angles, and as we just saw, two acute angles cannot add up to 180 degrees.

#/_6#: Look at the placement of angles 5 and 6. They are both on the diagonal transversal (a line/180 degrees), which makes them supplementary.
