$19 if the ( mangle dac = 74^{circ} ) then what is ( mangle cab )?$

$\angle DAC$ and $\angle CAB$ are complementary angles (they form a right - angle, so $m\angle DAC + m\angle CAB=90^{\circ}$).

Let $x = m\angle CAB$. We know that $74^{\circ}+x = 90^{\circ}$. Then $x=90^{\circ}-74^{\circ}$.

$16^{\circ}$
