Sin A 7 divided by 25
Brums [2.3K]

Answer:

Cos A = 24/25, Tan A = 7/25

Step-by-step explanation:

Given that Sin A = 7/25

Sin = Opp/hyp

Therefore using Pythagoras theorem, adjacent will be;

= √(25²-7²)

= √576

= 24

Thus;

Cos A = adjacent/hypotenuse

          =  24/25

Cos A = 24/25

Tan A = opp/hypotenuse

         = 7/25

Tan A = 7/25
