A=1/2bh ,b=…………….

Area of a triangle is given by A = 1/2 bh. If b= 12 cm and h=7cm find the area of the triangle.

._(1)^(2)H is called ……………..

Let a_(1), a_(2), …., a_(10) be in A.P and h_(1), h_(2),…. , h_(10) be I H.P if a_(1) = h_(1) = 2 and a_(10) = h_(10) = 3, then a_(4) h_(7) is

If H_(1), H_(2), ….. H_(n) are n harmonic means between a and b ( ne a), then the value of (H_(1) + a)/(H_(1) - a) + (H_(n) + b)/(H_(n) - b)

In Delta ABC is H is the orthocentre of Delta ABC and x= AH, y=BH, z=CH, then x+y+z=

If H is the orthocentre of DeltaABC and AH=x, BH=y, CH=z then (abc)/(xyz)=

IF H is the orthocentre of Delta ABC and if AH=x, BH=y, CH=z, then a/x+b/y+c/z=

e^((sec h ^(-1)""(1)/(2)+tan h^(-1)""(1)/(2)+sin h^(-1)""(1)/(2))=
