Question

SinA=12/13 then cotA=​

Answer 1

Answer:

cotA= 5/12

Step-by-step explanation:

let us take a triangle abc right angled at B

if sinA=12/13 then,

BC=12 and,

AC=13

now, by pythagora's theorem,

AB=5

now,

cotA= adjacent/opposite =5/12

Answer 2

Answer:

13/5

Step-by-step explanation:

sinA=12/13

sinA=height/Pythagoras

h=12

p=13

b=

$\sqrt{ {13}^{2} - {12}^{2} } = 5$

now,cotA=p/b

that is

13/5
