Question

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

Answer 1

Answer:

cosA=12/13

so, base=12 and hypotenuse=13

then,perpendicular=2√13

so,

sinA=2√13/13

and tanA=2√13/12

Answer 2

Answer:

Sin A=5/13 tanA=5/12

Step-by-step explanation:

Cos A=12/13=b/h

B=12

H=13

P=5

Sin A =p/h=5 /12

Tan A=p/b=5/12
