Ответ:
21.25
Step-by-step explanation:
a^2+b^2=c^2
the hypotenuse is c^2 which is also the diagonalyou put the 12.75 in the spot of the a, you could put the 17 in the spot of the b, and c^2 stays the same.you should get 162.5625 for 12.75^2.you should get 289 for 17^2add 162.5625 and 289 together to get 451.5625.after that u square root it to get 21.25 as your answer.
