C. because u can't name a congruent triangle by angle angle angle
The sqrt of 2, -5.41 and -5(pi) are all irrational numbers.
Irrational numbers are numbers that cannot be represented by simple fractions.
When two lines intersect each other then the vertically opposite angles are equal. Then the correct option is A.
<h3>What is an angle?</h3>
Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
The diagram is shown.
We know that when two lines intersect each other then the vertically opposite angles are equal.
Then
x = 52° because they are vertically opposite angles.
Thus, the correct option is A.

Because there's an even number of values in this set, there is two middle values rather than one (31 and 34). To find the median we need to add them together and divide the sum by 2 (31 + 34 = 65, 65/2= 32.5) Our final answer is 32.5.
