Answer 1

${\large{\purple{❥}}}$${\large{\underline{\red{\sf{Answer:}}}}}$

${\large{\bold{\sf{Given, \:sinA = 3/5}}}}$

${\large{\bold{\sf{cosA = \sqrt{1-sin²A}}}}}$

${\large{\bold{\sf{cosA = \sqrt{1-(3/5)²}}}}}$

${\large{\bold{\sf{cosA = \sqrt{4/25}}}}}$

${\large{\bold{\red{\sf{cosA = 2/5}}}}}$

${\large{\bold{\sf{tanA =sinA/cosA}}}}$

${\large{\bold{\sf{tanA =(3/5)/(2/5)}}}}$

${\large{\bold{\red{\sf{tanA =3/2}}}}}$
