If the angles of `/_ABC` are in ratio `1:1:2`, respectively (the largest angle being angle C ), then the value of `(sec A)/(cosec B)-(tan A)/(cot B)` is

If the angles of DeltaABC are in ratio 1:1:2, respectively (the largest angle being angle C), then the value of (secA)/("cosec"B)-(tanA)/(cotB) is

If the angles of DeltaABC are in ratio 1:1:2 , respectively (the largest angle being angle C), then the value of (secA)/(cosecB)-(tanA)/(cotB) is:

If the angles of triangle ABC are in the ratio 1:1:2 respectively (the largest angle being angle C ), then the value of (Sec A)/(Cosec B) - (tan A)/(Cot B) is : (a) 0 (b) 1:2 (c) 1 (d) (sqrt3)/2

If triangle ABC is right angled at C, then the value of sec (A+B) is

If the angles of a triangle are in the ratio 1:4:7 , then the value of the largest angle is :
