Explanation:
We can assume that:
the 12 foot ramp to the entrance of a building is the base of a right angled triangle and the 3 feet above the ground should be the height above the ground basement. The by using the tangent of a triangle from the knowledge of our trigonometric function; we have:


The degree measure of the angle of elevation is 14.04°
NO, it doesn't fit the requirements.
We can increase the foot ramp to 34 feet instead of being the 12 given value in order to fit the requirements.
Answer:
Explanation:
The refractive index of the suspected glass can be known by using the backe- line method. This process takes place in a petrographic microscope. In this method an oil comparable to the refractive index of the glass is used. At a point when the refractive index of the glass becomes equal to that of the oil in which it is immersed the yellow line under the observation of the plane polarized light gets disappeared. This method can be used to identify the refractive index of the suspect glass and comparing it with the source of origin or sample glass.
