Question

Find x.

The value of x is

Answer 1

`\sqrt {77} \approx 8,77496438739`

Explanation:

With a known theorem, the square of the height relative of the hypotenuse is equal to the product of the projection of the sides on the hypotenuse itself.

In our case,
`x^2 = 7* 11 \rightarrow x = √(77) \approx 8,77496438739`
