8 0

Step-by-step explanation:

Because 2x and 40° are complementary angles.

\therefore \: (2x) \degree + 40 \degree = 90 \degree \\  \\  \therefore \: (2x) \degree  = 90 \degree  - 40 \degree \\  \\ \therefore \: (2x) \degree  = 50 \degree  \\  \\ \therefore \: 2x  = 50  \\  \\  \therefore \: x  =  \frac{50}{2}  \\  \\ \huge \red{ \boxed{ \therefore \: x  = 25}}
