Question

If A and B are acute angles and cosec A=secB, find the value of A+B​

Answer 1

Answer:

cosec (90-A)=Sec (90-B)

secA=sec(90-b)

sec to sec cancel

now,A+B=90degree

Answer 2

Answer:

Hey there

cosec A = sec B

Resiprocaling both the sides,

sin A = cos B

sin A = sin (90 - B)

A = 90 - B

A + B = 90

Hence, A + B = 90
