The figure is a square. Its diagonals meet to form four right angles. What is the approximate value of x? 2.8 units 3.3 units 4.0 units 5.7 units

since the side of the square is equal to 8 and x is half the length of the diagonal. The value of x can be solve using Pythagorean theorem. Since is only half the leng the diagonal

(2x) ^2 = 8^2 + 8^2

4x^2 = 128

X^2 = 32

X = 5.7
