as,sinA=4/5 ,cosA=3/5

therefore,cotA=cosA/sinA=3/4

Answer 2

Answer:

Here, The value of CotA is 3/4.

Step-by-step explanation:

Here, As per our given question,

SinA=4/5 =Perpendicular(P)/hypotenuse(h)

So, By applying pythagoreas theoren we will get the value of Base(b):

=H^2=P^2+B^2

=B^2=H^2-P^2

=B^2=(5)^2-(4)^2

=B^2=(5+4) (5-4)

=B^2=9×1

=B^2=9

By doing square root on both sides, we get,

=B=9 units

Now, As asked in our question,

CotA=B/p

=CotA=3/4

So, Here the value of CotA=3/4.

Thank you.
