Answer:
x<−3
Step-by-step explanation:
hope this works
Answer:
Never
Step-by-step explanation: If two points are on the same plane but a line containing those two points is not on the same plane, the statement will never be true. Picture a cube and on one face of the cube lies two points, if there is a line containing those points, the line also has to be on the same side or face. It will always run parallel to the same side but will also always be touching that side.
Complimentary angles, when added, = 90 degrees
so if one angle is x, then its compliment is 90 - x
x = 5(90 - x) - 6
x = 450 - 5x - 6
x + 5x = 450 - 6
6x = 444
x = 444/6
x = 74
and its compliment is : 90 - x.....90 - 74 = 16 <==
Answer:
8 vertices
Step-by-step explanation:
Use Euler's Theorem: V-E+F=2
F=12
E=18
Thus, we have:
V-18+12=2
V-18=-10
V=8
So there are 8 vertices
