Question

Solve for the missing side multiple choice please answer

Answer 1

Answer:

The answer is option 3 .

Step-by-step 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

${x}^{2} = {9}^{2} + {7}^{2}$

${x}^{2} = 81 + 49$

${x}^{2} = 130$

$x = \sqrt{130}$

Answer 2

Answer:

x= square root of 130

Step-by-step 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
