I´d say "d" is the distance from the eye to the wall.
Now substracting 1.2-1 you´ll get the distance of the wall of the smallest triangle = 0.2 And you do 1.5-0.2= 0.3 that´s the distance of the wall of the other triangle. Then you solve everything with Pitagoras theorem. You have 2 rectangle triangles.
B+alfa=45°
tan^-1(0.2/d)=B
tan^-1(1.3/d)=alfa
THEN:
tan^-1(0.2/d)+tan^-1(1.3/d)=45°
Now you have 3 ecs and 3 variables.
alfa,B and "d"

Step 1
Collinear points are a set of three or more points that exist on the same straight line. Collinear points may exist on different planes but not on different lines.
Step 2
Graph the points; (-5,2),(0,6),(6,4)
Step 3
Conclude based on step 2
Since the points are not a straight line, we can conclude that the 3 points are not collinear.
Answer:
<em>D. 30</em>
Step-by-step explanation:
6 ÷ 1/5 <em>-given expression</em>
6 x 5 <em>-use the </em><em>keep, change, flip </em><em>method, where you</em><em> keep</em><em> the </em><u><em>first </em></u><em>number, </em><em>change</em><em> the </em><u><em>division sign</em></u><em> to a </em><u><em>multiplication sign</em></u><em>, and </em><em>flip</em><em> the f</em><u><em>raction</em></u><em> that comes after the symbol.</em>
<em>6 x 5 = 30</em>
<em>30 is the answer</em>
