Answer:
an isosceles triangle
Step-by-step explanation:
3.1567 * 10^-4 miles
1 ft = 1.894 * 10^-4 miles , so
1 inch = 1.894 * 10^-4 / 12 miles
= 0.15783 * 10^-4
= 1.5783* 10^-5 miles ( in scientific form).
Multiplying this by 20 we get
31.567 * 10^-5
= 3.1567 * 10^-4 miles.
= -4 + 12 + (-9)
= -4 + 12 - 9
= -4 + 3
= -1
116.55$
