Ineed the answer for both of these fast .

1): 15, 2): 5

Step-by-step explanation:

I used the Pythagorean Theorem which is .

For 1), the equation is (12*12) + (9*9) = c*c OR 144 + 81 = c*c. I got 225 = c*c. Then I used a calculator to figure out the square root of 225 and I got 15.

For 2), the equation is (4*4) + (3*3) = c*c OR 16 + 9 = c*c. I got 25 = c*c. Then I used the calculator to figure out the square root of 25 and got 5.

i'm assuming it's looking for the missing length, which should be 4cm

hope this !
