Question

Can somebody answer these 2 questions

Answer 1

For 2 the answer is 12. For 3 the answer is 28.

Explanation:

These may be wrong but hopefully they are correct

My work:

`5^2+11^2=146` then
`√(146) = 12.08`

`√(421)=20.5`
`19^2+20.5^2=781.25` then
`√(781.25) =28`

Answer 2

2. 12.08

3. 7.74

Explanation:

a squared + b squared = c squared

2. 5 squared = 25, 11 squared = 121, 25 + 121 = 146, the squre root of 146 is 12.08

3.19 squared = 361, 421 - 361 = 60 60 squared = 7.74
