Question

Solve for x. Leave your answer in the simplest radical form.

Answer 1

Answer:

x = 2$\sqrt{5}$

Step-by-step explanation:

'x' can represent the hypotenuse of a right triangle with a base of 4 (11-7) and a height of 2

use Pythagorean Theorem to find 'x':

2² + 4² = x²

4 + 16 = x²

x² = 20

x = $\sqrt{20}$

x = $\sqrt{4}$·$\sqrt{5}$

x = 2$\sqrt{5}$
