The answer would be 56/299
Answer:
Step-by-step explanation:
Given question is incomplete: Find the compete question in the attachment.
a). Skew lines neither the parallel lines nor they intersect each other.
Two pairs of skew lines are BF and EH, & CG and EF.
b). Since EFGH and ABCD are rectangular planes and BF and DH are perpendicular to them,so both will be the altitudes between the planes.
Therefore, BF and DH will pe parallel.
c). BD and DH are the diagonals of the planes parallel to each other.
Therefore, BD and DH will be parallel.
d). Since BD and plane EFG don't intersect each other, so the solution will be an empty set.
e). HG is perpendicular to DH. So,the planes BDH and FHG containing these lines will be perpendicular to each other.
You are absolutely correct, be more confident and practice, you got this :)
Answer:
it's not a geom progression
Step-by-step explanation:
Answer:
2 : 3
Step-by-step explanation:
Given ratio of sides of 2 similar triangles = a : b , then
ratio of areas = a² : b²
Here by working in reverse
ratio of areas = 4 : 9 , thus
ratio of sides =
:
= 2 : 3
