Awheelchair ramp needs to be pitched at 8 degrees. if the ramp is to access an 18-inch step to a door what will be the length of the ramp to the nearest inch?

Answer : The length of the ramp to the nearest inch will be, 129.49

Step by step explanation :

As we know that,

In the given image, the value of (the angle between the base and the hypotaneous) is and the value of perpendicular is 18 inch.

Now we have to calculate the value of the hypotaneous by using above expression, we get

The hypotaneous is equal to the length of the ramp = 129.49 inch

Therefore, the length of the ramp to the nearest inch will be, 129.49

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
