$\huge{\boxed{\text{ Solution:- }}}$

_____________

¶Given:-¶

tan(A) = 0 and sin(A) = 0

_____________

¶To find:-¶

cos(A)

_____________

¶Solution:-¶

◆ tan(A) = 0

=> tan(A) = tan(0°)

◆ sin(A) = 0

=> sin(A) = sin(0°)

After viewing both the above equations, we can conclude that,

$\boxed{∴ ∠A = 0°}$

∴ Substituting value of ∠A in cos(A),

=> cos(0°)

$\boxed{ => 1}$
