The sides of the triangle are in the ratio 3: 2 : 4 for if the perimeter of the triangle is 27 cm find the length of the each side

Correct Answer - 1 `9x^(2)-24xy+16y^(2)-12x+16y-12=0` or `(3x-4y+2)(3x-4y-6)=0` Hence , the distance between the lines is `(|6-(-2)|)/(5)=(8)/(5)`.

sides are  1)9 cm 2) 6 cm 3) 12 cm. .... respectively

Correct Answer - C `v=l^(3)` `(dv)/(dt)=3l^(2)((dl)/(dt))` `((dv)/(dt))=3(2)^(2)(10^(-4)m^(3)//sec)` `((dv)/(dt))=12xx10^(-4)m//sec`

Correct Answer - 9 cm Let the length of the shotest side of the triangle be x cm . Then length of the longest side = 3 x cm Length of...

Correct Answer - `120^(@)` Let the sides be `x - d, x, x + d`. Then `s = (3x)/(2), (s -a) = (x)/(2) + d`, `(s-b) = (x)/(2), (s-c) = (x)/(2)...

Correct Answer - A Given that `4A + A + A = 180^(@)` or `A = 30^(@)` Angle are `120^(@), 30^(@), 30^(@)` `rArr (sin 120^(@))/(a) - (sin 30^(@))/(b) = (sin 30^(@))/(c)...

Correct Answer - D Sides are in the ratio `1 : sqrt3 : 2` Let `a = k, b = sqrt3 k, and c = 2k` `cosA = (b^(2) + c^(2)...

Correct Answer - C `a = 2b and A - B = 60^(@)` We know that `tan.(A -B)/(2) = (a -b)/(a + b) cot.(C)/(2)` or `tan 30^(@) = (1)/(3) cot.(C)/(2)` or...

Correct Answer - B Let a, b and `c(a lt b ltc)` be the sides of given triangle. Also, `2r = a + b - c` ltbr when `r = 4`...
