Dakota Fitzpatrick · Answer 1

D. 15cm because

9^2+12^2=c^2

81+144=225

225=c^2

Natalee George · Answer 2

C. 15 cm

Step-by-step explanation:

The equation for finding the hypotenuse is A squared + B squared = C squared.

Lets use 9 as A and 12 as B.

9 times 9 is 81. 12 times 12 is 144.

81 + 144 = 225.

The square root of 225 is 15.

The answer is C) 15 cm
