Plz help me I’ve been stuck on this question

If one leg of a right triangle is 9 units and the other leg is 12 units what is the length of the hypotenuse in units

I think its 15

Step-by-step explanation:

a(squared) +b(squared) =c(squared)

so

12×12=144

9×9= 81

144+ 81= 225

and the square root of 225 is 15

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
