1.

If sinA = 1/3 Then find the value ofCOSA and Tan A

Answer»

Answer:

COS A =

$2 \sqrt{2 } \div 3$

and tan A =

$1 \div 2 \sqrt{2}$

Step-by-step explanation:

SINA =1/3=perpendicular / hypotenois
in a right angled triangle ABC,B is at right angle
BC =1 and AC =3
AB =
$\sqrt{ {3}^{2} - {1 }^{2} }$
AB =
$\sqrt{9 - 1}$
AB
$\sqrt{8}$
AB =
$2 \sqrt{2}$
