Question

If cosecA= SecB,then prove that A+B= 90°

Answer 1

Answer:

Step-by-step explanation: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
