Answer: 4,111.7 mm³
Step-by-step explanation:
You need to use this formula to calculate the volume of the square pyramid:

Where "s" is the lenght of any side of the square base and "h" is the height of the pyramid.
Find the height with the Pythagorean Theorem:

Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle. Let be "c" the height of the pyramid.
You can identify in the figure that:

Then, you can find the height:

Then, knowing that:

You can calculate the volume:

Answer:
.
Step-by-step explanation:
Two angles are supplements of one another if their sum is
.
Two angles are complements of one another if their sum is
.
Let
be the measure of the angle in question.
The supplement of this angle would be
.
The complement of this angle would be
.
According to the question:
.
Solve this equation for
:
.
Thus, this angle would measure should
.
The supplement of this angle would measure
. The complement of this angle would measure
.
Three times the complement of this angle would be
, which is indeed
greater than the supplement of this angle.
.690 because 6 rounds up to 10 so it would go up to the next tenth
