Question

If cot A = 3by5 find sin A and cos A
​

Answer 1

Answer:

sin A=P/H = 5/√34

cos A = B/H = 3/√34

Step-by-step explanation:

cot A = B/P=3/5

B=3 k , P=5 k  ( k= any value or constant )

find hypotenuse

H²=P²+B²

H²=9+25

H=k√34

sin A=P/H =5 k/k√34= 5/√34 ( k cancel )

cos A = B/H = 3 k /k√34 = 3/√34 ( k cancel )
