Answer:
Two trapezoids labeled V R A S and B U W D. Sides B U and V R contain one tick mark. Sides B D, U W, V S, and R A each contain two tick marks. Sides A S and W D each contain three tick marks. The angles represented by vertex letters U, B, R, and V each contain two tick marks. The angles represented by vertex letters D, W, S, and A each contain one tick mark.
Answer:
V=12
Step-by-step explanation:
Faces: 20 Edges: 30
Write the Euler's formula for 3-dimensional figures
F+V=E+2
Substitute some variables for their known values
20+V=30+2
Add the numbers on the right side of the equation
20+v=32
Subtract 20 on both sides
20-20+V=32-20
Subtract
V=32-20
Number of Vertices
V=12
Answer:
Hello!
~~~~~~~~~~~~~~~~~
1.2n+1=1-n
=
n = 0
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
