I don’t know how to do this ! Help?

Answer:

The information we need is that the angle between the sides (that is, angle TVU for triangle TVU and angle WVX for triangle WVX) need to be equal.

These angles are vertically opposite angles, because they are formed by two lines crossing, so these angles are equal.

Step-by-step explanation:

The SAS Congruence Theorem says that if two triangles have 2 equal sides and the angle between these sides are also equal, the triangles are congruent.

In this question, we know that the sides UV and VW are congruent, as V is the midpoint of UW. We also know that TV = VX, so now we have two equal sides for each triangle.

The information we need is that the angle between the sides (that is, angle TVU for triangle TVU and angle WVX for triangle WVX) need to be equal.

These angles are vertically opposite angles, because they are formed by two lines crossing, so these angles are equal.

Now we can conclude that the triangles are congruent.

By taking x as subject the formula becomes x = (v² - u²)/2a.

<h3>What is Equation?</h3>

An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.

Here given equation:

      v² = u² + 2ax

     2ax = v² - u²

      x = (v² - u²)/2a

Thus, by taking x as subject the formula becomes x = (v² - u²)/2a.
