उत्तर
If the angles of ∆ABC are in ratio 1:1:2, respectively (the largest angle being angle C), then the value of `"secA"/"cosecB"-"tanA"/"cotB"` is 0.
Explanation:-
1x +1x +2x =180°, x = 45°.
∠A , ∠B and ∠C are 45°, 45° and 90°resp.
`"secA"/"cosecB"-"tanA"/"cotB"="sec 45"/"cosec 45"-"tan 45"/"cot 45"=sqrt2/sqrt2-1/1=1-1=0`
