The surface area of the square prism is 115 square inches
<h3>surface area of a pyramid</h3>
The surface area of a pyramid is equivalent to the sum of the faces of the pyramid
For the given square pyramid;
TSA = (5*5) + 4(1/2 * 9 * 5)
Simplify to have;
Surface area =25 + 4(45/2)
Surface area = 25 + 180/2
Surface area = 25. + 90
Surface area = 115 square inches
Hence the surface area of the square prism is 115 square inches

It's an isosceles triangle so angles A and BCA are congruent.
Angle BCA is the supplement of BCD, so 180-109 = 71.
Angle A is congruent to that, so A=71 degrees.
Let's see if we can get that in the format they want, kind of as a proof.
1. ∠BCD=109° Reason: Given
2. AB ≅ BC Reason: Given
3. ∠BCA = 71° Reason: Linear pairs are supplementary
4. ΔABC is isosceles. Reason: Definition of isosceles
5. ∠A ≅ ∠BCA Reason: Isoceles triangle theorem
6. ∠A = 71° Reason: Def congruent
Answer: 71 degrees
24 + 44 = 4(6 + 11) (Answer A)
4(12 + 22) ← 4 is not the greatest, 12 + 22 = 2(6 + 11)
6(4 + 11) ← this is 24 + 66
2(12 + 6) ← this is 24 + 24
