Question

if cosecA=15/7 and A+B=90 find the value of secB

Answer 1

cosec A = 15/7
cosec(90-A)=15/7
sec B =15/7
hope it will help u!

Answer 2

here,

we know that,
cosecA=sec(90-A) . ..................(1)

A+B=90

therefore,
B=90-A..............................(2)

COSECA=15/7
sec(90-A)=15/7 from(1)

secB=15/7............................from(2)

we get,
secB=15/7
