Answer:
Option C.
Step-by-step explanation:
Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.
Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.
Using triangle proportionality theorem we get
On cross multiplication we get
Divide both sides by 9.
The length of SA is 3ft.
Therefore, the correct option is C.
Answer:
Part A) Is a square
Part B) Is a rectangle
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The figure show a rectangular prism with a square base
Part A) A cross section formed by a plane that intersects the prism parallel to its base would take the shape of a
we know that
A cross section is the intersection of a figure in three-dimensional space with a plane
A plane parallel to the base of a rectangular prism will intersect a cross section that is the same shape as its bases.
so
The cross section is a square
Part B) A cross section formed by a plane that intersects the prism perpendicular to its base would take the shape of a
we know that
A plane perpendicular to the base of a rectangular prism will intersect a cross section that is the same shape as its lateral faces
so
The cross section is a rectangle
