Question

Please help i need helpppppp

Answer 1

first option

Explanation:

using pythagoras theorem

a^2 + b^2 = c^2

x^2 + 10^2 = 12^2

x^2 + 100 = 144

x^2 = 144 - 100

x^2 = 44

x =
`√(44)`

x = 6.63

Answer 2

15.62

Explanation:

`a^(2) +b^2=c^2`

`10^2+12^2=c^2`

`100+144=c^2`

`c^2=244`

`√(244) =` 15.62
