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
Unit price = $3.84/12 = $0.32
The answer is 80%
