Answer:
Jamie is correct
Step-by-step explanation:
Jamie is correct.
Example: isosceles triangle ABC AB=AC
∠B = ∠C ∠A + ∠B + ∠C = 180°
if ∠A = x ∠B = ∠C = 1/2 * ( 180° - x)
if ∠B or ∠C = x ∠A = 180° - 2x

Answer:
400 units³
Step-by-step explanation:
The volume (V) of the square pyramid is
V = area of base × height (h)
where h is the perpendicular height.
Consider the right triangle formed by a segment from the vertex to the midpoint of the base and the slant height ( the hypotenuse )
Using Pythagoras' identity on the right triangle
h² + 5² = 13²
h² + 25 = 169 ( subtract 25 from both sides )
h² = 144 ( take the square root of both sides )
h = = 12
Area of square base = 10² = 100, hence
V = × 100 × 12 = 4 × 100 = 400
