7 0

Step-by-step explanation:

cos \: x = sin \: (2x + 57) \\  \\  \therefore \: sin(90 \degree -  \: x) = sin \: (2x + 57) \\  \\ \therefore \:90  -  \: x = 2x + 57 \\  \\ 90   + 57  \:  = 2x + 3 \\  \\ \therefore \:3x = 147  \\  \\ \therefore  \: x =  \frac{147}{3}  \\  \\  \huge \orange{ \boxed{\therefore  \: x = 49 \degree}}
