Okay so I have no clue what to do on these problems lol. Can someone help explain it please? Thank you

you use the Pythagorean theorem (a^2 +b^2 = c^2)

a^2 +17^2 = 19^2

a^2 + 289 = 361

a^2 = 72

a = (square root)72

5^2 + 13^2 = c^2

25 + 169 = c^2

194 = c^2

c= (square root)194

a^2 + 10^2 = 20^2

a^2 + 100 = 400

a^2 = 300

a = (square root) 300

5^2 + 14^2 = c^2

25 + 196 = c^2

221 = c^2

c= (square root) 221

Step-by-step explanation:

it says to leave it as it's simplest radical form, i can't put a square root on the screen, but put the number inside the radical and leave it like that.

I hope this helps :)

its the fourth option

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!
