Question

If sin A=3/5
find (1) cos A (i) cot A​

Answer 1

Answer:

CosA=4/5

CotA=4/3

Step-by-step explanation:

Since SinA=3/5

We know that SinA)=perp/hyp

Also, (hyp)"=(perp)"+(base)" ["=square]

(base)"=(hyp)"-(perp)"

(Base)" =(5)"-(3)"

=25-9

=16

Base=4

Now, CosA=base/hyp

=4/5

CosA=4/5

CotA=base/perp

=4/3

CotA=4/3

Answer 2

Answer:

Cos A:-4/5

Cot A:-4/3
