Step-by-step explanation:
The dimensions of the pyramid, expressed in ancient Egyptian units of measurement, were 280 cubits high, a base length of 440 cubits, with a seked of 512 palms (a slope of 51°50'40").
Triangles ABC and XYZ are similar, so the corresponding angle to A in XYZ triangle is angle X. We can actually find sin(X) very easily.
Because we know all sides and the right angle, we can use certain formula to find sin(X), like this:
sin(X) = opposite side / hypotenuse = 6/10 = 3/5
sin(X) = sin(A)
The correct answer is sin(A) = 3/5.
