Answer
$\sin A = \frac{40}{58}$
$\cos A =\frac{42}{58}$
$\tan A = \frac{40}{42}$
$\csc A = \frac{58}{40}$
$\sec A = \frac{58}{42}$
$\cot A = \frac{42}{40}$
Work Step by Step
SOHCAHTOACAO RULE
$\sin A = \frac{o}{h} = \frac{40}{58}$
$\cos A = \frac{a}{h} = \frac{42}{58}$
$\tan A = \frac{o}{a} =\frac{40}{42}$
$\csc A = \frac{h}{o} =\frac{58}{40}$
$\sec A = \frac{h}{a} =\frac{58}{42}$
$\cot A = \frac{a}{o} =\frac{42}{40}$
