Answer:

√(25 - 9A²) / 3A

Step-by-step explanation:

5CosA - 3A = 0

CosA = 3A/5 = Adjacent side to A /Hypotenuse

Cos²A + Sin²A = 1

Sin²A = 1 - (3A/5)² = 25 - 9A²/25

SinA = √(25 - 9A²) / 5

TanA = SinA/CosA =  √(25 - 9A²) / 5 / 3A/5 =   √(25 - 9A²) / 5  * 5/3A

                                =√(25 - 9A²) / 3A
