Answer:
QT and ST
RS and SW
Step-by-step explanation:
There are 2 of the answer choice that are correct. QT and ST, RS and SW.
Those lines do intersect each other at a corner of the cube.
I believe the answer is 2/1, or 2 over 1.
For the first problem, we use the trigonometric function cosine. The equation would be:
cos (1/2)θ = 3960 / (3960 + 90)
Solving for θ
θ = 24.20°
Solving for the distance the satellite can see:
s = rθ
s = 3960 (24.20) π/180
s = 1672.79 mi
The satellite can see1672.79 mi of distance.
For the second problem, we approach the reverse manner as the first problem.
Solving for the angle,
θ = s/r
θ = 3000 / 3960
θ = 0.7576 (180/π) = 43.41°
Solving for h:
cos 1/2 (43.41) = 3960 / (3960 + h)
h = 302.19 mi
The satellite must be 302.19 mi above the Earth.
