we know that
in the triangle ABC
<span>applying the Pythagorean theorem
AC</span>²=AB²+BC²
<span>AC=8 cm
AB=apothem
BC=9.4/2-----> 4.7 cm
AB</span>²=AC²-BC²-----> 8²-4.7²-----> 64-22.09------> AB²=41.91
AB=√41.91-------> 6.47 cm---------> 6.5 cm
apothem=6.5 cm
the answer is
6.5 cm

Answer:
Sandy will finish the race first.
Step-by-step explanation:
Let D be the total one sided distance in miles, ( between X and Y ),
We know that,
Since, from point X to point Y and back, Jack averages 30 miles per hour to point Y and 10 miles per hour back to point X.
So, the total time taken by Jack =
Also, Sandy averages 20 miles per hour in both directions,
So, the total time taken by Sandy =
∵ 0.133D > 0.10D
Hence, Sandy will finish the race first.
