This would equal (9+25)/2
Which could be simplified into 34/2
Which means the answer is 17
Answer:
<em>The shortest possible length for the service road is 2.88 miles.</em>
Step-by-step explanation:
According to the below diagram,
and
are the positions of airport, shopping center and factory respectively.
Given that,
and 
In right triangle 

The shortest possible length for the service road from the shopping center to the highway that connects the airport and factory is
.
That means,
is also a right triangle in which
, Hypotenuse
miles and
is the opposite side in respect of
or
.
Now in right triangle 

So, the shortest possible length for the service road is 2.88 miles.
The missing angle is 13.6, since we got the sides we can find the hypotenuse of 8 and 11 and that is 13.6 ||
Making the answer: 13.6
Here is my math c=a2+b2=8.2+11.2≈13.60147
