Answer:
Surface area of pyramid = 1536 square inches.
Step-by-step explanation:
Surface area of a pyramid with the square base will be = surface area of base + 4× slant surfaces of the pyramid
area of square base = 24×24 = 576 inches²
area of one slant side of pyramid = (1/2)×side × slant height = (24×20)/2 = 240 square inches
Therefore surface area of complete pyramid = 4×area of slant side + surface area of square base = 4×240 + 576 = 960 + 576 = 1536 square inch.

Answer:
11° and 79°
Step-by-step explanation:
Complementary angles sum to 90°
let x be one angle then the other angle = x + 68 , hence
x + x + 68 = 90
2x + 68 = 90 ( subtract 68 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
The 2 angles are x = 11° and x + 68 = 11 + 68 = 79°
As a check : 11 + 79 = 90
