(52)/(x)=sqrt((169)/(289))cos5x200

If (52)/(x)=sqrt((169)/(289)), the value of x is (a) 52 (b) 58 (c) 62 (d) 68

Solve the equation: (4sqrt((cos x)/(2))-5-(sqrt(2))/(2))^(2)+sqrt(2)(4sqrt((cos x)/(2))-5-(sqrt(2))/(2))-(cos x)/(2)=0

sqrt((324)/(49))xx sqrt((676)/(169))xx(126)/(sqrt(81))=x

sqrt(144)+sqrt(169)=?^(2)

Find the value of x in the equation ((sqrt(324))/(sqrt(49)))((sqrt(676))/(sqrt(169)))((126)/(sqrt(81)))=x

Solve the equation: (4sqrt(cos x/2)-5-(sqrt(2))/2)^2+ sqrt(2)(4sqrt(cos x/2)-5-(sqrt(2))/2)-(cosx)/2=0

Evaluate: sqrt(3(33)/(289))

If (52)/(x)=(169)/(144) , find the value of x.
