Answer:
The answer is Tangent.
Step-by-step explanation:
Given that Tangent Rule is tanθ = opposite/adjacent. In this question, opposite is 11, adjacent is x and θ is 21°.
So using this formula, you are able to find the value of x.
Answer:
Three times
Step-by-step explanation:
Given
Figures: Rectangular Prism and Rectangular Pyramid
Let the dimension of the prism be:



Amount of sand used is the volume (V1) and it is calculated using;


Since the pyramid has the same base area and height as the prism, the its dimension would be:



Amount of sand used is the volume (V2) and it is calculated using;

So, we have:


Substitute lwh for V1 in the second equation

Multiply both sides by 3


Reorder


<em>Hence, the amount of sand used in building the prism is three times the amount of sand used in building the pyramid</em>
