Question

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

Answer 1

Answer...

$\sin(a) = \frac{opposite \: side \: }{hypotenuse}$

= 5/17

$cos(a) = \frac{adjacentside}{hypotenuse}$

= 8/17

$\tan(a) = \frac{sin \: a}{cos \: a}$

= 5/8
