Question

If sin A= 1 /2then the value of Cot A is:​

Answer 1

2…....................

Answer 2

Answer:

sin A =1/2 = perpendicular /hypotenuse

let the perpendicular = x

Hypotenuse = 2x

by Pythagoras theorem,

B=√ H2-P2

B = √ (2x)2 - x2

B = √ 4x2 - x2

B= √3x2

B = x√3

cot A = base /perpendicular

= x√3/x

=√3
