Question 380765: Trigonometric functions describe relationships between the angles and lengths of the sides of a right triangle. Give a real world example showing how this can be used. Be sure to include the specific trig relationship that would be used in the situation you describe. If possible, include a diagram to show the relationships. (IN TEXT)

A block slides down a frictionless ramp, where the ramp has a given angle (theta) above horizontal. What is the acceleration of the block?
We need trig to figure out that the acceleration is g sin (theta) where g is the gravitational acceleration of Earth. The solution involves decomposing the weight force into horizontal and vertical components (to form a right triangle), where the x and y axes are parallel and perpendicular to the ramp's surface, respectively.
