THE ANSWER IS EQUILATERAL BECAUSE THEY ALL HAVE EQUAL SIDES
Ok so imagine G=gasoline and D equals the discounted price
It would be G-20=D
∠BDC=30, so ∠CBD + ∠BCD=180-30=150
ΔDBC is isosceles, so ∠CBD=∠BCD=half of 150=75
∠ABC=∠ABD-∠CBD=155-75=80
ΔABC is isosceles, so ∠ABC=∠ACB=80
∠BAC=180-80-80=20
This does not appear to make sense, could you perhaps add signs such as multiplication, division, etc.
What you have to do is take the cube root of eight and 1000 and get your answer. The answer would be 2/10.
