In Figure, if `y/x=5` and `z/x=4,` then the value of `x` is (a) `8^0` (b) `18^0` (c) `12^0` (d) `15^0`

In Figure,if (y)/(x)=5 and (z)/(x)=4, then the value of x is 8^(0)( b) 18^(0)(c)12^(0) (d) 15^(0)

In the figure, if A B=A C ,/_B A D=30^0 and A E=A D , then x is equal to a) 15^0 (b) 10^0 (c) 12. 5^0 (d) 7. 5^0

If cos x=tan y,cos y=tan z,cos z=tan x then the value of sin x is (a)2cos18^(0)(b)cos18^(0)(c)sin18^(0)(d)2sin18^(@)

If x y z=0, then find the value of (a^x)^(y z)+(a^y)^(z x)+(a^z)^(x y)= (a)3 (b) 2 (c)1 (d) 0

If x y z=0, then find the value of (a^x)^(y z)+(a^y)^(z x)+(a^z)^(x y)= (a)3 (b) 2 (c)1 (d) 0

If the system of equations x+a y=0,a z+y=0 and a x+z=0 has infinite solutions, then the value of a is (a) -1 (b) 1 (c) 0 (d) no real values

If (-4,0) and (1,-1) are two vertices of a triangle of area 4s qdotu n i t s , then its third vertex lies on (a) y=x (b) 5x+y+12=0 (c) x+5y-4=0 (d) x+5y+12=0

If (-4,0) and (1,-1) are two vertices of a triangle of area 4s qdotu n i t s , then its third vertex lies on (a) y=x (b) 5x+y+12=0 (c) x+5y-4=0 (d) x+5y+12=0

If x > 0, y > 0, z>0 and x + y + z = 1 then the minimum value of x/(2-x)+y/(2-y)+z/(2-z) is: a. 0.2 b. 0.4 c. 0.6 d. 0.8
