Question

In right angle triangle $ABC,8cm,15cm$ and $17cm$ are the length of $AB,BC$ and $CA$ respectively. Then, find out $\sin A,\cos A$ and $\tan A$

Answer 1

According to question,

Angle B =${90}^0$

for angle$A$

base(B)=$8cm$

perpendicular(P)=$15cm$

hypotensue(H)= $17cm$

$sinA=\frac{P}{H}$

$=\frac{15}{17}$

$cosA=\frac{B}{H}$

$=\frac{8}{17}$

$tanA=\frac{P}{B}$

$=\frac{15}{8}$
