Question

if cos A = 12/13 then what is the value of sin A
​

Answer 1

Answer:

cos a = c0s b aand is tiapwn skPoww

Answer 2

Step-by-step explanation:

CosA=12/13

B/H=12/13

By pythagoras theorem

H^2 = B^2 + P^2

(13)^2 = (12)^2 + p^2

169 = 144 + p^2

169-144 = p^2

25 = p^2

p = 5

Now,

Sin A = P/H

= 5/13

This is your answer....
