Answer:
90°
Step-by-step explanation:
Since, all sides of the given quadrilateral are equal. Therefore it is rhombus.
Diagonals of a rhombus bisects at right angles.
So, x = 90°
Answer:
they are congruent
Step-by-step explanation:
Answer:
91.3 in³
Step-by-step explanation:
The formula for the volume of a pyramid is:
V =
where B=area of the base and h=height of the pyramid
Given the dimensions in the problem and that the pyramid has a square base, we can first calculate the area of the base:
A = 7.4 x 7.4 = 54.76 in²
Multiply the area of the base x height of the pyramid: (54.76 x 5) = 273.8
Divide by 3 (multiply by
): 273.8/3 ≈ 91.3 in³
