as you know

a^2 + b^2 = c^2

so, plug in your numbers

7^2 + b^2 = 11^2
49+b^2 = 121
b^2 = 72
b = √72 = 8.5
find the perimeter of the shape below
do yall know the other ones
Answer
1:B; 8.5
2:A; 9.4
3:C; 1,1
4:A; -2
5:D; 4/3
6:B; 1
7;D; y= 2x-5
8:B; 30
9:C; y=9x+ 2/3

These are 100% correct so I hope it helps👍
@Heyo Is not 100%. sucks that I was the first person to test that, but I will tell you guys what 100% should look like.

1. 8.5
2. 9.4
3. (1, 1)
4. -2
5. 4/3
6. -2
7. y = 2x - 5
8. 30
9. y =2/3 + 9
