What is the area of the triangular floor space enclosed by the glass tetrahedron? Round to the nearest tenth of a square foot. Enter only the number.
( Hint : Look at the green triangle to find the base, b , of each green triangle. Because b is also the hypotenuse of the right triangle formed by dividing the base triangle into half, you can use this and Heron’s formula for the area of the triangle.)
Height 105 ft
Angle of depression is 21.9
Side lengths are 167
Base is 260

what does "base 260" mean in all this?
Maybe a fuller description of the tetrahedron's sides, and what the green triangle involves.
angle of depression from what to where?
