x^3-10x^2=27x-18=0 has no solutions
x^3-10x^2-27x-18=0 has 3 solutions
x^3-10x^2-27x-18=0 also has three solutions
Assuming the side lengths did not change, ...
Angle C would need to decrease by the same amount.
Angles B and D would each need to increase by the amount angle A decreased.
First, we are going to find the distance traveled by the ship adding the tow distances:
Distance traveled= 24 mi +33 mi=57 mi
Next, we are going to use the Pythagorean theorem to find the distance from

to

:


d^2=1665


mi
Finally, we are going to subtract the two distances:
57 mi -40.8 mi= 16.2 mi
We can conclude that <span>if the ship could have traveled in a straight lime from point a to point c, it could have saved
16.2 miles.</span>
Answer:B:72
Step-by-step explanation:
Because you are doing multiplication and division in this problem
72°
the sum of the exterior angles of a polygon = 360°
for a pentagon with 5 sides the
exterior angle =
= 72°
