Answer 1

To find out the value of x in the triangle, we can see that x is the hypothenuse of the triangle. Then we must use the hypothenuse formula in a triangle:

`\begin{gathered} h^2=\text{ c}^2\text{ + c}^2 \\ h^2=\text{ 7}^2\text{ + 3}^{2\text{ }} \\ h^2=\text{ 49 + 9} \\ h^2=58 \\ √(h)\text{ = }√(58) \\ h=\text{ 7.6} \end{gathered}`

The x value is 7.6.
