Perpendicular lines have the negative reciprocal slope, so the slope of your new line will be -1/4 and the current equation will be as follows:
y = -1/4x + b
(where b is the y intercept)
to find b, plug in point A and you'll get:
2 = -1/4(16) + b
2 = -4 + b
6 = b
the equation will be:
y = -1/4x + 6
we know that
The measurement of <u>the external angle</u> is the semi-difference of the arcs which includes
so
m∠LMN=
therefore
the answer is 
Answer:
point A.
Step-by-step explanation:
B would be 2.5 and point a is in the middle or -4 and -3 which would make it -3.5
24-3x=2x-1
+3x. +3x
24=5x-1
