a). \ \

\

To calculate the complement of $\"\"$ \ \

\

$\"\"$ (Subtract angle from $\"\"$ ) \ \

\

$\"\"$ (Subtract: $\"\"$ ) \ \

\

To calculate the supplement of $\"\"$ is \ \

\

$\"\"$ (Subtract angle from $\"\"$ ) \ \

\

$\"\"$ (Subtract: $\"\"$ ) \ \ $\"\"$

\

b). \ \

\

To calculate the complement of $\"\"$ , subtract angle from $\"\"$ . \ \
