Answer:
C
Step-by-step explanation:
transposition
3x/4=1/5
xc=yc
15x/20×20=4/20×20
15x=4
x=4/15
Answer:
The answer to your question is these lines are not perpendicular.
Step-by-step explanation:
Data
A (4, 2)
B (-1, 4)
slope = m = 4
Perpendicular lines mean that these lines cross and form an angle of 90°. Also, the slope of perpendicular lines is negative reciprocals.
Process
1.- Find the slope of the second line and compare it to the slope given.
slope = 
Substitution
slope = 
Simplification and result
slope = 
-2/5 is not a negative reciprocal of 4, so these lines are not perpendicular.
ANSWER
Area of triangle = b*h/2
24*20/2
24*10
The area of this triangle is 240 ft squared
