Actually Welcome to the concept of Equilateral triangles.
Since the above triangle is a equilateral triangle, that has all sides equal and also all angles are equal,
by applying the angke sum property of triangle we get as,
==> 6x + 6x + 6x = 180°
hence, 18x = 180°
==> x = 180/18 ==> 10°
hence the value of x = 10°

The missing diagram is shown below. Remember that shapes are similar if you can turn one into the other by moving, rotating, flipping, or scaling. So this means you can make the object bigger or smaller. So in this case, we know that ΔABC is similar to ΔDEF. If so, we can establish the following proportion:
Our goal is to find x. So by Pythagorean theorem:
Conclusion:
<em>ΔABC ~ΔDEF</em>
