Answer:
A
Step-by-step explanation:
The volume (V) of a pyramid is
V = area of base × perpendicular height (h)
area of square base = 4² = 16 and h = 4, hence
V = × 16 × 4 =
= 21

Answer:
Step-by-step explanation:
Given:
An isosceles triangle ABC with AB = AC.
∠A =
∠B =
∠C =
We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.
Therefore, ∠B = ∠C
⇒
⇒
∴ ∠C = °
Now, the sum of all the interior angles of a triangle is always 180°.
Therefore, the value of 'y' is 5.
