Answer:
you anwser is a tetrahedron
Step-by-step explanation:
The angle of elevation from point C to point A is 
<em><u>Solution:</u></em>
Given that we have to find the angle of elevation from point C to Point A
Given in figure that, angle A = 
Given is a right angled triangle ABC where angle B = 
We have to find angle C
The angle sum property of a triangle states that the angles of a triangle always add up to 180°
Therefore, in given triangle ABC
angle A + angle B + angle C = 180


Therefore angle C = 
Well, 5/6 of an hour is 50 minutes. 3/8 of 50 is 6.25. 6.25 times 3 is 18.75.
I believe 18 minutes and 45 seconds.
D is your answer
plug in the x value and y value to the equation
when x = 1, and y = 4
-1 + 4 = 3
when x = 5, and y = 8
-5 + 8 = 3
hope this helps :D
