Question

Solve for the missing side multiple choice please answer

Answer 1

The answer is option 3 .

Explanation:

In order to find x, you have to use Pythogaras Theorem, c² = a² + b² :

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

Let a = 9,

Let b = 7,

Let c = x

`{x}^(2) = {9}^(2) + {7}^(2)`

`{x}^(2) = 81 + 49`

`{x}^(2) = 130`

`x = √(130)`

Answer 2

x= square root of 130

Explanation:

a^2+b^2=c^2

a=7 b=9 c=x

49+81=x^2

130=x^2

square root of 130=x
