Answer:
Step-by-step explanation:
16 divided by 2 4/5
change 2 4/5 to an improper fraction
2 4/5 = (5*2+4)/5 = 14/5
16 divided by 14/5
copy dot flip
16 * 5/14
rearrange to make the math easier
16/14 *5
8/7 *5
40/7
7 goes into 40 5 times with 5 left over
5 5/7
the formula for the Pythagorean theorem is a squared plus b squared is equals to c squared we don't have our a so it will be 8 * 8 =64which is 64 is equals to 10 * 10 which is 100 - 64 is equals to 36 then you square root do square roots the 36 which is 6
