Answer
complement: $74\frac{2}{3}^o$
supplement: $164\frac{2}{3}^o$
Work Step by Step
RECALL:
Supplementary angles have a sum of 180 degrees.
Complementary angles have a sum of 90 degrees.
The complement of the given angle is:
$=90^o-15\frac{1}{3}^o
\\=74\frac{2}{3}^o$
The supplement of the given angle is:
$=180^o-15\frac{1}{3}^o
\\=164\frac{2}{3}^o$
