Lets remember the property "alternative-interior angles" when we have parallels lines:
Given two paralles lines, the following is true:
In our question, we have:
We know that the angles J + P + K=180
So, the triangles have all the angles the same, so they are similar by angle-angle-angle, and they have one side congruent, AC=CD, so the triangles are congruents.
Hello! quartiles divide data into fourths, and percentiles divide data into hundredths! hope this helps! ;)
Answer:

Step-by-step explanation:
The scientific notation:

We have:

Y is 163 degrees because it is a vertical angle with the other 163 degree angle and vertical angles are equal.
