in³ are the units associated with volume, V. Arletha's measurement could represent volume.
_____
Area, B, would have units of in². Height, h, would have units of in.
X = 0
<span>6y - 5x = 0 so it intersects x=0 at (0,0)
</span>
<span>x + 3y = 21
</span>so it intersect x=0 at (0,7)
multiply by 2
<span>2x + 6y = 42
subtracting 6y - 5x = 0
7x = 42
x = 6
so the third line intersects w second line at (6,5)
6. area of triangle = 1/2*base*height
= 1/2*7*6
=21
7. volume = volume of 2 cones
cone volume = 1/3*pi*radius^2*height
lower cone: radius=6, height=5
upper cone: radius=6, height=7-5=2
volume = 1/3*pi*6^2*(5+2)
=84pi
=263.89

Answer:
Beta is 60 degrees, and the angle of A should be 30 degrees.
Step-by-step explanation:
Its a right triangle, so it equals 180 degrees, there's a perpendicular angle at 'C' so its 90 degrees, B and its angle of 'Beta' 60 degrees, and angle 'A' can be 30 degrees. if in need of more explanation please look into complimentary and supplementary angles should give you a good idea.
