Equation Solution – The Solve command does not work (I'm a beginner)

I try to execute the equation

9.897527129 = 9.780327  left (1 + 0.0053024  sin ^ {2} {x} -0.0000058  sin {2x}  right)

written

                To solve[9.897527129 == 
   9.780327 (1 + 0.0053024 (Sin[x]) ^ 2 - 0.0000058 Sin[2 x]) && -90 <=
x <= 90, x, reals]

I actually press Shift + Enter and nothing happens. Can you find out what is wrong?

Thank you in advance for your answer
