Question

If Cos A = 12/13 find Sin A and Tan A
​

Answer 1

Answer:

cosA =12/13

squaring

cos^2A=144/

sin^2A = 1-cos^2 A

=1-144/

tanA = sinA/cosA

Answer 2

Answer:

given - cos A 12/13

Step-by-step explanation:

sin^2 theta + cos^2 theta = 1 use this identity after using this trigonometric identity you will get sinA = 5/13 now for TanA use sin theta / cos theta = tan theta you will get tan A = 5/12. hope it will help you.
