Question

In $\Delta ABC$,right angled at $B$ if sides $AB=4$cm , $BC=3$cm and $AC=5$cm. Then match the following

• A. $\frac{3}{4}$
• B. $\frac{4}{5}$
• C. $\frac{3}{5}$
• D. $\frac{5}{4}$

Answer 1

From the given information, we can construct the triangle as shown below

as we know
$\sin C=\frac{4}{5}$,
$\cos C=\frac{3}{5}$,
$\tan A=\frac{3}{5}$,
$\sec A=\frac{5}{4}$
