Question

In the figure, AB = 5, AC = 13, then find sin A, cos C, sin A cos A, tan A. Also verify (i) tan A cos A (ii) sin A= cos C( give ans with explanation)​

Answer 1

Answer:

In the figure, AB = 5, AC = 13, then find sin A, cos C, sin A cos A, tan A. Also verify (i) tan A cos A (ii) sin A= cos C( give ans with explanation)

Answer 2

Answer:

BC = 12 cm

Sin A = p/h = 12/13

Cos C = b/h = 12/13

Cos A = b/h = 5/13

Verification :

Tan A = p/b = 12/5

=¹²/13/

⁵/13 = Sin A / Cos A

=> Sin A = Cos C = 12/13
