Question

Q1) Sin A=4/5, find Cos A and Tan A.

Answer 1

Answer:

3/5 , 4/5

Step-by-step explanation:

SinA = opposite side /  hypotenuse = 4/5

opposite= 4units; hypotenuse = 5units

adjacent side = square root of h²-(side1)²

adjacent side = 3

cos A = adjacent side / hypotenuse = 3 / 5

tanA = opposite side / adjacent side = 4 / 3
