A business is building a handicap accessible ramp at the enterence of the building. They want the slope to be a 1:10 ratio. In 1 - 2 sentences, explain how to find the angle of elevation of the ramp using inverse sine. What is the angle of elevation to the neares tenth of a degree? Show all your work.(3 points)
To find the angle of elevation of the ramp using inverse sine, calculate the inverse sine of the slope ratio (1/10). The angle of elevation is then equal to the inverse sine of 1/10, which is approximately 5.7 degrees.
Angle of elevation = sin^(-1)(1/10)
Angle of elevation = sin^(-1)(0.1)
Angle of elevation ≈ 5.7 degrees
