P = sqrt(27.8*exp(5*x)-1) == cos((120*x^2+sqrt(2*x))/(17*x-65))^(-1)

There are multi-solution with real data type:
x: 0.806253525595036
or
x: 1.29507590447776

Ran in:
syms x
P = sqrt(27.8*exp(5*x)-1) == cos((120*x^2+sqrt(2*x))/(17*x-65))^(-1) ;
s = vpasolve(P,x)
s =

Ran in:
syms x real
P = sqrt(27.8*exp(5*x)-1) == acos((120*x^2+sqrt(2*x))/(17*x-65)); % better to use acos function
s = double(vpasolve(P,x))
s = 0.0654 - 32.1398i
