Answer:
BC = 28 
ft
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
12BC = 340 ( divide both sides by 12 )
BC = 
= 
= 28

Answer: m=6, m=-4
Step-by-step explanation:
To solve this proportion, we have to cross multiply.
Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.
Combine like terms.
We can move all terms to one side and then solve for m.
We can actually factor this to:
We set each factor equal to 0 to find m.
m-6=0
m=6
m+4=0
m=-4
Answer:
never
Step-by-step explanation:
Intersecting planes are planes that intersect along a given line.
To explain this better, consider the following definitions:
i. A point: This is denoted by a dot and it is a location marked on a space or a plane.
ii. A line: This is the distance between two points. It is one-dimensional.
iii. A plane: This is a two-dimensional, flat surface with no thickness formed by points and extends infinitely.
Therefore, since intersecting planes intersect along a line, it is not possible that they intersect in exactly one point given that a line is the distance between points.
