please help

Answer 2

do you have a choice in mind?

Answer 3

B

Answer 4

third one
12 ,9 ,15
as 12^2+9^2=15^2[pythagoras theorem]

Answer 5

can u explain how it is the third one

Answer 6

like he said...you just do trial and error...pythagorean theorem states that \[a^2 + b^2 = c^2\] where a and are the legs and c is the hypotenuse...in Model C the hypotenuse is 15 and 9 and 12 are the legs....we use pythagorean theorem

\[\large 9^2 + 12^2 = 15^2?\] \[\large 81 + 144 = 25?\] \[\large 225 = 225 \checkmark\]

Answer 7

that's a and b are the legs*

Answer 8

okay thank you
