In a ABC, if tand: tan B:tan C=3:4:5, then the value of sinA.sin B.sin C is equal to then COS.X Cos y a) tan(a+B-Y) tany tan(o-B+y) tan tanß= 26. If tan-x+tan 2x + tan 3x=tan xtan 2x tan 3x then √3 2 2√5 7 2√5 3) 1) √5 9 25. In a APOR, if 3sin P+4cosQ=6 und 4sinQ+3 cos P=1, then the angle R equal to 5% TU 3r 4 6 Fr007ICAL C 3+sin 1+ 3sin² x Numerical Value type questions sin3x+cos3x| COS.x 27. If -2 and cos(x-y)=- then tan y = Cos y 28. If sine, sin 0₂ -cose, cose, +1=0, then the value of tan(0, /2)cot(0₂/2) is equal to 3r 30. The value of tan(a+B). given that coto= α€ π, 3) 31. If sin0=3sin(8+20) then the value of tan(0+0)+2 tance is 32. The value of sin230-sin260-sin290+.
