Answer:
"Can't be determined"
Step-by-step explanation:
From the triangles given in the picture,
Given:
m∠A = m∠C
m∠B = m∠D
But for the congruence of these triangles third condition is not given.
Therefore, congruence of these triangles can not be determined.
So the answer is "Can't be determined"
Explanation:
The square base of the pyramid has four sides with length 15 inches, making its perimeter four times that, or 60 inches. The slant height is
112×60=90 inches.
Therefore, the area of the base is B=152=225 square inches.
Each of the four lateral triangles has area 12⋅15⋅90=675 square inches.
The total surface area is 225+4⋅675=2,925 square inches.
