Question

If cos A =12/13 then find sin A and tan A ​

Answer 1

Answer:

cos A = 12/13

sin^2A + cos^2 A = 1

Answer 2

Answer:

Step-by-step explanation:

If cosA = 12/13

=> B = 12 and H = 13 (b/h = cosA)

SinA = P/H

12² + p² = 13²

p² = 25

p = 5

=> SinA = 5/13

=> Tan A = p/b

=> TanA = 5/12
