Slope of a line that is perpendicular to the given line is -6.
The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Answer:
Step-by-step explanation:
The perimeter is the sum of the lengths of the sides: 5 ft + 12 ft + 16 ft = 33 ft.
The area is found using the formula A = (1/2)(b)(h), where b = length of base and h = altitude. Here,
A = (1/2)(5 ft)(8 ft) = 20 ft^2
A=1/2 b x h
A= 1/2 (5 x 8)
A=1/2 (40)
so you divide 40 by 1/2
20
b) EB Perpendicular CA
c) AD Perpendicular CE
d) CF Perpendicular AE
Answer:
The statement is true is CF Perpendicular AE .
Option (d) is correct.
Step-by-step explanation:
As given
∠AFC = ∠EFC
Let us assume that the measure of ∠AFC be x.
Thus
∠AFC = ∠EFC = x
As
∠AFC + ∠EFC = 180° (By Linear pair property)
x + x = 180°
2x = 180°
x = 90°
Thus
∠AFC = ∠EFC = 90°
Therefore CF is perpendicular to AE .
Option (d) is correct.
