$\texttt{Question}$

Given : sin A= ³/5

find

i) tan A

ii) cos A

iii) sin A ²+ cosA²

$\texttt{Answer}$

Given,

$SinA=\frac{3}{5}$

$o {}^{2} + o {}^{2} = h {}^{2}$

$3 {}^{2} + o {}^{2} = 5 {}^{2}$

$o {}^{2} = 25 - 9$

$o {}^{2} = 16$

$0 = 4$

Here we have

Opposite side =3

Adjacent side=4

Hypotenuse =5

According to question

i) tanA

$= \frac{3}{4}$

ii)CosA

$= \frac{4}{5}$

iii) sin A ²+ cosA²

$( \frac{3}{5}) {}^{2} + ( \frac{4}{5} ) {}^{2}$

$\frac{9}{25} + \frac{16}{25}$

$\frac{25}{25}$

$= 1$
