Answer:
0.93
Step-by-step explanation:
Add the total faces: 30 + 20 + 12 = 62
Using the given equation: V + F = E +2
You have F = 62, V = 120
Now solve for E:
120 + 62 = E +2
Simplify:
182 = E +2
Subtract 2 from both sides:
E = 182 - 2
E = 180
It has 180 edges.
Answer:
Proof :- In triangle QDA and UAD
1. QD=UA (GIVEN)
2. ANGEL QDA=UAD (GIVEN)
3. DA =AD ( COMMAN BASE)
THEREFORE, TRIANGLE QDA IS CONGRUENT TO UAD (BY SAS RULE)
