Answer:
ABC are the marked vertices (points) of a triangle. They join each line ie) A to B= AB A to C= AC B+C=BC. We can when working on combined lines and shapes call the exterior vertices away from the triangle D and E when making reference to finding measurements of adjoining shapes/lines, but not to ABC. We can also use AB to determine the midway point as a independent or alternative use.
We usually see A on the opposite point of a right angle.

Answer:
(a) y = -3/4x +36
Step-by-step explanation:
The slope of the rail is ...
m = rise/run = -9/12 = -3/4
The initial height of the rail is 36, so the slope-intercept equation for the rail is ...
y = mx +b . . . . . m = slope; b = initial value
y = -3/4x + 36
Hexagon, s<span>um of i</span><span>nterior angles = 720
so
x = 720 - (115 + 120 + 115 + 135 + 120)
x = 720 - 605
x = 115</span>
