f(x) = 4x2 + 5x – 2 g(x) = 5x – 2x2 – 3x + 4 Which function represents the sum of the functions, h(x) = f(x) + g(x)? h(x) = 5x + 2x2 + 2x + 2 h(x) = –x2 + 2x + 2 h(x) = 5x – 4x2 + 4x + 2 h(x) = 5x + 2x2 – 2x – 2

40 degrees

Step-by-step explanation:

The answer is 40 degrees. Angle x and angle y form vertical angles, therefore x = y. Angle y forms a straight line with the 80° angle and the 60° angle which means that 80° + 60° + y = 180°. 140° + y = 180°. y= 180° - 140°. y = 40°. As mentioned earlier: x = y, so x = y = 40°.

Hope this helps
