Complementary angle of third angle is #pi/8# and supplementary angle of third angle is #(5pi)/8#

Explanation:

As the two angles are #pi/8# and #pi/2#, the third angle is

#pi-pi/2-pi/8=(8pi)/8-(4pi)/8-pi/8=(3pi)/8#

As complementary angles add up to #pi/2#,

its complementary is #pi/2-(3pi)/8=(4pi)/8-(3pi)/8=pi/8#

As supplementary angles add up to #pi#,

its complementary is #pi-(3pi)/8=(8pi)/8-(3pi)/8=(5pi)/8#
