Find sin A and cos A A) sin A = 3/5; cos A = 4/5
B) sin A = 4/5; cos A = 3/5
C) sin A = 5/4; cos A = 4/5
D) sin A = 4/3; cos A = 3/4

We found sinA= 3/5 and cosA=4/5

Option A is correct.

Step-by-step explanation:

The formula to find sin A is :

while the formula to find cos A is:

So, in the figure given:

Base = 16

Perpendicular = 12

Hypotenuse = 20

Now, finding sin A and cos A using formulas and above values

So, we found sinA= 3/5 and cosA=4/5

Option A is correct.
