Answer:
Lines BC and F represent perpendicular lines
Step-by-step explanation:
we have
<em>Line BC</em>

the slope of the line BC is 
<em>Line F</em>

the slope of the line F is 
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so

we have
-----> slope line BC
-----> slope line F
Find the product of their slopes

therefore
Lines BC and F represent perpendicular lines
1 and 17/20 should be the answer
I think its B. Because 396 divided by 3 equals 132 (there's 3 feet in a yard)
The answer is c or the third one
Y is 6 and x is 2 I have shown my work in the picture pls ask any questions
