Question

IF 5 cot B=12 the find the value of CosecB+SecB​

Answer 1

Answer:

coseB + secB = 221/60 ✔✔

Step-by-step explanation:

Given that,

5cotB = 12 ,

So, we get, cotB = 12/5

As tanB = 1/cotB ,

We get, tanB = 5/12

We know the two formulas, they are :

cosec²B - cot²B = 1 and

sec²B - tan²B = 1 ,

By using the above two formulas, we get as,

cosecB = 13/5 and

secB = 13/12 ,

So, coseB + secB = 13/5 + 13/12

coseB + secB = 221/60
