45:81 is equivalent to 85/x then value of x is

if (45)/(60) is equivalent to (3)/(x) then value of x is

If (45)/(60) is equivalent to 3/x , then the value of x is 3 (b) 6 (c) 4 (d) 9

If (3)/(4) is equivalent to (x)/(20) then value of x is

If (45)/(60) is equivalent to 3/x , then x= 5 (b) (4) (c) 6 (d) 20

If 2 sin ^(2) x + cos ^(2) 45^(@) = tan 45^(@) and x is an acute angle, then the value of tan x is :

If 57:X ::51:85, then the value of x is

If 57:x::51: 85, then the value of x is

If 4:5:: x:45, then the value of x is

If tan x = sin 45^@. cos 45^@ + sin30^@ , then value of x is - यदि tan x = sin 45^@. cos 45^@ + sin30^@ हो, तो xका मान क्या होगा ?
