The correct answers are:1) sin(x) =
2) tan(x) =
Explanation:Given:

Step 1:
Since, according to the Trigonometric identity:

-- (1)
Step 2:
Plug in the value of cos(x) in equation (1):

Step 3:
Take square-root on both sides:

sin(x) =

Now to find the tan(x), we would use the following formula:
tan(x) =

--- (2)
Plug in the values of sin(x) and cos(x) in equation (2):
tan(x) =

Hence tan(x) =
2 lines I think, not sure though

Answer:
cubic meter of clay will be used to create all the pyramids
Step-by-step explanation:
The remaining part of the question is given in the attached file
Solution
The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.
For Rectangular Pyramid,
Volume of three rectangular pyramids

Substituting the given values in above equation, we get -
cubic centimeter
For triangular Pyramid,
Volume of two triangular pyramids

cubic centimeter
Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid
Cubic centimeter
