Question

If cosA= root 3/2





then cotA is?​

Answer 1

cosA = root3/2

A= 30° or A=330°

cotA = +- 1/ root3

Answer 2

Answer:

cot a is$\sqrt{3}$/1

Step-by-step explanation:

in a triangle abc right angled at b  then,

cos a=ab/ac=$\sqrt{3}$/2

so, ab=$\sqrt{3}$,ac=2

then bc=1 [by pythagoras theorem]

cot a=ab/bc=$\sqrt{3}$/1
