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 
9514 1404 393
Answer:
D. 7
Step-by-step explanation:
The equation is ...
x = a(y +1)² -3
For the point (x, y) = (4, 0), we have ...
4 = a(0 -1)² -3
7 = a . . . . . . . . . . . . add 3, simplify
The leading coefficient is 7.
Step-by-step explanation:
it's explained in the solution

Hope this helps :)
2x-3y=6
3y=2x-6
y=2/3x-2
Slope = 2/3
Therefore B
