Quickly plz What is the value of x?
O liv units
O 2 13 units
O 2/3 units
O 3v3 units

Step-by-step explanation:

Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.

This means the length of the side to the left is also x as shown in the image below.

The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:

Operating:

Since 18=9*2

The options are not clear enough, so I cannot make a choice.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
