Answer:
Option a) 1/5 is most closely to 0.
Answer:
C is the answer.
Step-by-step explanation:
SinA=5root3/10
CosA=5/10
TanA=5root3/5=root3
SinC=5/10=1/2=0.5
CosC=5root3/10
Tanc=5/5root3=1/root3
Its d 729 because on 1 layer theres are 81 cubes and there are 9 layers so 81 times 9 equals 729
Hope this helps
