Question

if sin A= 3/4 then find cot A
​

Answer 1

Explanation:

$\frac{ \sqrt{7} }{3}$

is the value of cotA

Answer 2

Answer:

sin A=3/4

sin A formula=opposite side to A/hypotenuse

then opposite side=3

and hypotenuse=4

now we should find adjacent side

by Pythagoras theorem

hypotenuse square=side square+side square

here ^ means square

4^=3^+side^

side^=4^-3^

side^=16-9

side=√7

therefore adjacent side is √7

cot A =adjacent side to A/opposite side to A

cotA=√7/3

finally cot A = √7/3
