In the given figure,` x-a` is equal to `(1)b-y (2) b+y (3) y -b (4) -b-y `

If (a)/(x)+(y)/(b)=1 and (b)/(y)+(z)/(c)=1, then (x)/(a)+(c)/(z) will be equal to: (a) 0 (b) (b)/(y) (c) 1 (d) (y)/(b)

If x =a , y = b is the solution of the pair of equation x - y = 2 and x + y = 4 then the value of 3a + 4b is …….. .

If (sin (x+y))/( sin(x-y))=(a+b)/(a-b) , then (tan x)/( tan y) is equal to .............. A) b/a B) a/b C) ab D) a-b

If sin x+sin y=a and cos x+cos y=b then cos(x-y) is equal to (1)/(2)(a^(2)+b^(2)-2)(B)(1)/(2)(a^(2)+b^(2)+2)

((a-b)^2-(a+b)^2)/(-4a)=x/y . On simplifying the given equation, which of the following equations will be obtained? x y=b (b) b x=y (c) a b=x (d) y b=x (e) a y=x
