What is triangle similarity?

If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar.

Given are two triangles,

AA rule of similarity:

If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.

Here we see,

∠ K ≅ ∠ Y

∠ J ≅ ∠ X

Hence, we can say that, both are similar by AA rule.

find z and x

please help i’ll mark the first one or whoever right brainliest

Answers

Answer:

z=97 x=21

Step-by-step explanation:

so straight angles always equal 180°

And assuming that your lines are parallel, the angle under angle z should be 83° just like the angle above angle z

There for to solve for x, first subtract 83 from 180 because that's what that angle is equal to.

Now that you have the equation 4x+13 and you know that it's equal to 97 you can solve it just like a normal inequality.

4x+13=97

4x=84

x=21
