Question

if sinB = 12/13, then find cotB​

Answer 1

Answer

given

sinB = p/h= 12/13

base= ?

cotB = base/perpendicular

base=root 15

therefore ,

cotB= b/p= root 15/12 Ans..

Answer 2

AC square=AB square + BC square. = BC square = AC square- AB square. = (13) square - (12) square= 169-144=25 = 5. Answer = Cot B = 5/12
