Why is the axis of action also called the 180-degree system?
Kipish [7]
The answer is:
<span>
a. there are 180 degrees of space on the chosen side of the axis of action in which the camera may be placed to preserve screen direction.

The camera must not cross the imaginary axis line to avoid creating a "reverse angle". Simply saying, the camera must only shoot on one side of the scene.</span>

Answer: 63°

<u>Step-by-step explanation:</u>

Since BD is the diameter, then arc BCD = 180°

Given that arc BC = 54°, then arc CD = 180° - 54° = 126°

∠DBC is an intercepted angle -> DBC = half of arc CD

\angle DBC=\bigg(\dfrac{1}{2}\bigg)126^o\quad =\large\boxed{63^o}

Find the slope of the line that is ​(a) parallel and ​(b) perpendicular to the line through the pair of points.​ (−2​,−7​) and ​
densk [106]
Hey there! 

First, find the slope of the actual original pair of points.
The slope formula is:

m =  \frac{ y_{2} -  y_{1} }{ x_{2} -  x_{1} }

So now, substitute the points in, whichever order you substitute the points into the equation doesn't matter, as long as the ones substituted in with the same subscript number.

m = \frac{ -7 - 4 }{ -2 - 8 }\

Once you subtract, you get:

m = \frac{-11 }{ -10 }

So the slope is 11/10.

A line that is parallel to another has the exact same slope that that another line has.

So therefore the line that is parallel has a slope of 11/10.

Perpendicular is another story. You take the reciprocal of the slope of the other line, and then change the sign before it: ex: negative would become positive.

So therefore the line that is perpendicular has a slope of -10/11.
