Question

if sinA= 1/2 then the value of cot A is
(a)√3 (b)1/√3 (c)√3/1 (d) 1 please give me answer fast
​

Answer 1

Answer:

It can be root 3 and root 3/1 because both are same

Step-by-step explanation:

sinA= Perpendicular/Hypotenuse

sinA=1/2

By Pythagoras Theorem,

In Triangle ABC, with base= BC=?

height= AB=1

hypotenuse = AC=2

AC^2= AB^2+BC^2

BC^2= AC^2-AB^2

BC= root(AC^2-AB^2)

BC= root(2^2-1^2)

BC= root(4-1)

BC= root(3)

cotA=1/tanA=Base/Perpendicular

cotA= root(3)/1

=root(3)
