Explanation Given: f ( x ) and g ( x ) are two given function. Formula used: sin ( − x ) = − sin x Calculation: f ( x ) and g ( x ) are two even function. f ( − x ) = f ( x ) g ( − x ) = g ( x ) Consider the functional equation z ( x ) = f ( x ) + g ( x ) . z ( − x ) = f ( − x ) + g ( − x ) z ( − x ) = f ( x ) + g ( x ) z ( − x ) = z ( x ) Therefore, z ( x ) is an even function. This shows that the sum of two even functions is always an even function. f ( x ) and g ( x ) are odd function. f ( − x ) = − f ( x ) g ( − x ) = − g ( x ) Consider the functional equation z ( x ) = f ( x ) + g ( x )

Rylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lb
