A business is building a handicap accessible sidewalk at the entrance of the building. They want the slope to be a 1:12 ratio. In 1–2 sentences, explain how to find the angle of elevation of the ramp by using inverse trigonometric functions. What is the approximate angle of elevation for the ramp? Round your answer to the nearest whole degree.(2 points)
To find the angle of elevation of the ramp, use the arctangent function with the slope ratio (1/12). The approximate angle of elevation for the ramp is 4.76 degrees.
