Answer:
x -2y = -4
Step-by-step explanation:
The slope of the line between points C and D is ...
m = (y2 -y1)/(x2 -x1)
m = (7 -13)/(5 -2) = -6/3 = -2
The slope of the perpendicular line is the opposite reciprocal of this: -1/(-2) = 1/2. The point-slope equation of the desired line is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -1 = 1/2(x -(-2))
We can rearrange this to standard form.
2y -2 = x +2 . . . . . multiply by 2
-4 = x -2y . . . . . . . subtract 2y+2
x -2y = -4 . . . . . . standard form equation of the desired line
V=A*h*1/3 - equation to count volume of the pyramid
A=93.5 sq ft
h=6 ft
V=93.5*6*1/3=93.5*2=187 cubic ft
say, you have half a pie, and 2 sisters, if you divide the half-pie in 3 equal pieces, how much is everyone getting of the whole pie? well, is the quotient of 1/2 and 3.
The answer is P, because if both triangles are right angled and have the angle of 70°, then because angles in a triangle equal 180° you can say that they will be the same as 70 + 90 = 160, and 180 - 160 = 20, which is the same steps for both triangles. I hope this helps! Let me know if I need to explain it further or anything :)
